For those new to Crypto the Mt Gox story is infamous. It was an exchange that was brought down by regulators in 2014 and many people who had their Bitcoin in there lost it all as a result. They still have not received their BTC and one person I know said they lost a million dollars in BTC there, as a result of the Mt Gox take down.

With the resent take down of Broker1 a US based exchange, it leads one to believe that Binance and Kraken may be next as the Bitcoin Exchange points out: https://bitcoinexchangeguide.com/sec-shuts-down-1broker-as-crypto-community-says-binance-and-bitmex-are-next/
If you have coins of value at all it's friendly reminder to try and get them off of an exchange, as to what happened to Mt Gox before would be devastating to some people if they lost their BTC or ETH. There are many ways to store your digital crypto off exchange on a Nano Ledger S, Desktop Based Wallets, or Mobile wallets. I recently put together a list of mobile wallets for this very reason to give people a guide on some of the best ones out there:

I hope these links and ideas give you some insight into what happened with Mt Gox, and that your money on Binance and other exchanges isn't very safe. If regulators step in and shut the site down you may never get your crypto back again, unfortunately if you don't take it out and put it into a wallet.
