We know this common phrase ‘not your key not your coin’. It is just about exchanges, they have the private keys, which means address they give to users are for the exchange owner and they have full control over any money their users send to the addresses. This can lead to inconveniences like blocked or freezer account, withdrawal maintenance, inability to access your coins and many other things that can come up.

Not only that, another are hackers. Many exchanges has been hacked in the past, many exchanges are hacked yearly, even Binance and some other trustworthy exchanges has been hacked before.

These are common reasons we should not leave our coins on exchanges. But how are traders helping themselves? Not to hold on exchanges is good for holders, but would be hard for scalpers and day traders.
