The Largest Cryptocurrency Exchanges: Who Runs Them and Why Hacks Keep Happening

Women Who Run Two of the Largest Cryptocurrency Exchanges

I was surprised when I read that two of the largest cryptocurrency exchanges are run by women. Most folks think crypto is a boys' club. But Gracy Chen runs Bitget, and Yi He helped start Binance. That's a big deal, and worth saying plain.

Chen grew up with a single mom. She says she was expected just to be happy and find a life partner. But from primary school she wanted to lead. At 18 she got a scholarship to study math in Singapore. Later she hosted a finance TV show in China and learned about Bitcoin at $300 back in 2015.

She read the Bitcoin white paper and was hooked. As a math person she liked the clean design. She liked that it was open to regular people. After that she started two small firms and did an MBA at MIT. In 2022 she joined Bitget as managing director. Now she is CEO with over 1,500 staff.

Yi He was born in 1986 in rural Sichuan. Her family were teachers. She was top of her class. She moved to Beijing to study psychology but found few jobs. Then she got a TV job in tourism. In 2013 she met Star Xu of Okcoin and joined as VP. Okcoin became a top exchange in China under her.

Unlike now, people weren’t interested in mental health at the time.

He brought CZ into Okcoin as CTO. CZ left in 2015 after fights with Xu. He stayed in and out of tech until 2017. CZ showed her his plan for a global exchange. She co-founded Binance with him in June 2017. Today Binance is the largest crypto exchange by far, with $36.5 billion in daily volume.

Scale and Fees of the Big Exchanges

When you look at the largest cryptocurrency exchanges, size varies a lot. Binance does $36.5 billion in daily trade and holds $134.6 billion in assets. Bitget does about $4 billion in volume. These are not small shops.

Fees matter if you trade. Binance charges 0.10% per trade. Coinbase Pro asks 0.50%. Kraken is 0.16% to 0.26%. KuCoin is 0.10%. Gemini is 0.35%. Deposit by bank is free on Binance. Withdraw fees change by coin.

Quick look at the big ones

If you want a review of crypto exchanges that is easy to read, the list above is a fair start. Coinbase is seen as trusted in many places. Gemini was made by the Winklevoss twins and leans hard on rules and safety. KuCoin has low fees but less oversight.

Where the Largest Cryptocurrency Exchanges Sit Legally

The largest cryptocurrency exchanges live under different laws. Some are in places with clear rules. Others are in places with no rules at all. Hong Kong only warns people. Samoa, Vanuatu, and Seychelles have no real crypto law.

Some countries folded crypto into old laws. Singapore, UK, and US did that. Japan and Malta made new crypto laws. Malta passed the Virtual Financial Assets Act. It lets exchanges fight claims and makes market tricks a crime with up to 6 years in jail.

Binance moved to Malta in March 2018. OKEx followed. At that time one quarter of all exchange volume came from Malta-based firms. The top three by volume - Binance, OKEx, Bitfinex - have all moved when the law climate turned bad, like China's ban.

Malta welcomed Binance in March 2018, with OKEx following soon after; at that time, one quarter of total cryptocurrency exchange volume came from those registered in Malta.

How Rules and KYC Work at Exchanges

Big centralized exchanges must follow local law. They use KYC and AML checks to stop crime. KYC means they know who you are. AML means they watch for dirty money.

Binance runs a KYC plan. If you skip it, you can take out only 2 Bitcoin a day. At one point that was over $110,000 a day. The CFTC checks if KYC really works. A leaked paper said Binance may have helped US users dodge the rules.

The CFTC watches much of crypto because many coins are commodities. Bitcoin and Ether are commodities by law. If you trade derivatives, the firm must register with CFTC. Binance did nearly $59 billion in derivatives at one point.

To keep US users out, Binance blocks by IP. If a US IP hits Binance.com it sends you to Binance.us. But VPN or Tor can beat that. So the wall is not solid. That's the weak spot regulators worry about.

Big Hacks That Hit Exchanges

Hacks are the scary part of crypto. Nobitex, the largest exchange in Iran, was hit and lost nearly $90 million. But the old hacks were worse. Three early ones took about $1.09 billion combined.

Mt. Gox was hacked from 2011 to 2014. Up to 850,000 Bitcoin gone. A weak password may have opened the door. Later, hackers got signing keys and drained it slow. Only 1811 coins were traced for sure.

Three early big hacks

Bitfinex lost keys in a multi-sig setup. No block stopped the big withdraw. Coincheck kept a hot wallet with no multi-sig. That made it easy prey. Best practice is simple: keep big funds off single hot wallets and use multi-sig.

Best practice: restrict large funds from single hot wallets; use multi-signature.

Other hits include Poly Network, where most funds came back. The 2022 Binance hack was mostly frozen by Binance. FTX lost about $400M and looks like an insider job. Ronin lost over $500M and was tied to North Korea.

What Makes an Exchange Secure

People ask what is the most secure crypto exchange like there is one clear winner. There is not. Gemini and Kraken push security hard. Binance has KYC but got hacked. Coincheck shows a hot wallet with no multi-sig is a bad idea.

New best steps are key care, hot wallet and vault setup, and smart contract checks. Most folks agree that clear rules for exchanges are the path to min safety bars. Without rules, each exchange picks its own lock strength.

If you use crypto exchange apps in usa , check if the app uses KYC and where the firm is based. A US-based app may follow US law. An app based in a no-law place may not help you if things go wrong.

Buying and Cashing Out Crypto

New users often want to know how to buy or sell cryptocurrency without stress. You pick an exchange, do KYC, add money, and trade. Coinbase is a common start in the US. Binance has more coins but more law noise.

Later you may ask how do i turn my crypto into cash . You sell on the exchange, then pull to your bank. Some places also let you sell via p2p. Fees and speed depend on the exchange and your country.

There is a gap between a user wallet and a firm wallet. Some ask difference between coinbase and coinbase wallet - one is the exchange where they hold keys, the other is your own app where you hold keys. Know which one you use before you send coins.

Is an Exchange a Safe Place to Invest

Folks also look for a legit crypto investment platform and hope the big name means safe. Size helps with liquidity but not with trust by itself. Read the fee, the law base, and the hack history before you park funds.

For wide choice, people scan best crypto trading websites and pick by coin count and fee. KuCoin has 700+ coins. Binance has 600+. But more coins can mean more thin markets and more risk.

Some use crypto com exchange web for simple buy and sell. Others go to niche spots. Tokocrypto is one such venue in Asia and is part of the Binance group. Pick what fits your country and your needs.

Centralized regulation is the most likely pathway forward for minimum cybersecurity standards.

Stablecoins and Exchange Listings

Stablecoins are big now. USDT moves about $703B a month. USDC runs large too. EURC grew fast after the EU made a stablecoin rule called MiCA. XSGD is a Singapore dollar coin by StraitsX.

XSGD went live on Coinbase and trades vs USDC. It also runs on Base, Coinbase's low-cost chain. MAS in Singapore says it fits the coming SCS rule. You can swap SGD and XSGD at zero fee and it settles 24/7.

In the US, the GENIUS Act pushed banks and funds to look at stablecoins before it took effect. The EU MiCA rule cleared the way for euro coins like EURC. These laws shape which coins an exchange can list.

How People Use the Big Exchanges Around the World

Adoption is wide. India, US, and Pakistan lead by grassroots use. APAC grew 69% in value received. Latin America grew 63%. Sub-Saharan Africa grew 52%. North America got over $2.2 trillion in crypto value.

By population, Eastern Europe leads. Ukraine, Moldova, and Georgia are top. Drivers are money trouble and tech skill. Low-income users show more ups and downs in use.

Bitcoin brings the most fiat in. It pulled $1.2T from Jul 2024 to Jun 2025. ETH got $724B. Stablecoins got $497B. USD is the top fiat ramp at $2.4T. South Korea is next at $722B.

Tokocrypto and Smaller Venues in the Mix

Not every name is a giant. tokocrypto exchange is smaller but part of the Binance network and serves Asia. It shows how the largest cryptocurrency exchanges often own or link to smaller ones to reach more users.

This link model helps users move between venues. But it also means a hack or law issue at the parent can touch the smaller arm. Keep that in mind when you pick where to trade.

Leadership Changes at the Top Exchanges

Binance shows how leadership shifts. CZ started it with Yi He. He is no longer in charge of ops. Now Yi He and CEO Richard Teng run the show. They speak out on where crypto should go.

Bitget stayed with Chen after she moved from director to CEO. That kind of steady hand is rare in crypto. Most top exchanges have seen founder exits, law fights, or both.

The largest cryptocurrency exchanges keep changing leaders, law homes, and security steps. But they stay the main door for most people to reach crypto.

Why the Regulation Gap Matters

The gap is real. Some exchanges sit under tight law. Some sit under none. That makes it hard for users to know their rights. A hack in a no-law place may leave you with no help.

Hong Kong only warns. Malta wrote a full law. US uses old rules plus new stablecoin talks. This patchwork means the same exchange may follow different rules by where it sits that day.

Hey, don't skip this part. If you store funds on an exchange, know its law base. It is the difference between a clear path to help and a dead end after a hack.

What I Take From All This

The largest cryptocurrency exchanges are not one thing. Some are led by women, some by men, some by teams. Some push low fees, some push safety, some push both and fail at one.

Hacks show that hot wallets and weak keys bite hard. Rules are uneven, so user care matters. Read the fee, the law base, and the hack record before you trust a venue with your coins.

I don't think crypto is going away. But the exchange layer is where most people meet it, and that layer is still rough. Plain info beats hype. Know who runs it and where the law stands.
