What crypto exchanges can you recommend?
It all depends on what youre after, they all have something that makes them different each starting from the looks, chart and a lot more. But if we what we are talking about is in terms of safety then I will recommend Coinbase. Coinbase is really one of the best exchanges you will come across and not only is it safe, but is also a good a exchange with extra features to offer including a secured wallet. Then we have Binance, OKEx, Bitfinex and a lot of them that are also good.
Coinbase also same as the other exchanges which maybe hacked since we are not in control of our wallets,we don't have to use the crypto exchanges to store our coins unless you are an active trader and also you need to keep in mind that it can be hacked any time so better move to wallets soon after the trades and coinbase may not be preference for all because where few coins were listed and they are adding more coins and tokens recently.
