Done a few trades there with zero hassle.
It depends on what coins you are using for trading purposes. If you stick to just Bitcoin and other top level altcoins, you are less likely going to face any sort of problems, which applies to all shitcoin exchanges. In other words, an exchange (especially when it concerns a shitcoin exchange) can be as good or shitty as you want it to be.
But I'm lately worried about all these exchanges, not because I think they want to scam us. Just much safer to keep your coins with you.
Lately? It has always been safer to keep your coins just with you instead of leaving them on exchanges. Also, you should be worried because of how they *might* scam you. Most of the times when an exchange gets hacked I very much doubt that it actually got hacked. It's far too easy as exchange operator to plan everything in the best possible way. Coincheck was not an exception. $500 million worth of crypto assets in hot wallets, hello, how obvious do people want to have it?
