Binance has no doubt, besides that I also use several other exchanges and I think that is pretty good, like kucoin, hotbit, livecoin etc. but you have to be careful lately some big exchanges have been hacked, nothing guarantees the security of these exchanges from hackers, it's wise to save your money on exchanges
Even if they hack Binance from now till tomorrow, Binance will always be the best, investors should keep their coin in their wallet and guard it themselves, we have a lots of wallets that are dedicated to this. Binance is to function as an exchange which they have been performing well in a very long time.
One great thing that really attracted me to Binance is their profit sharing idea with their community, a company that has the interest and happiness of their customers at heart, the hacking that happened to them really saddened my heart and I wished it has never happened, but I am glad they are now stronger than they were, with full force security tools already put in place now.
I share this position. The last hackers' attach to the exchange have shown that no one client felt this negative effect. Binance is the most reliable and powerful crypto exchange. nevertheless, if you trade actively, you should not limit or choice with one exchange only. Kraken is not bad at all - it is in the list of the most reliable and respected cryptocurrencies exchanges.
