In making your decision as regards the exchange to use for trading, one of the most important factor to be considered is the security of the platform. With the incessant issues of hacks and scam, its wise to consider if the exchange has a robust security mechanism in place, if 2FA is made available to users, the level of Authentication needed to login to the platform and make withdrawals, etc.
Yeah but there are some exchanges have complete feature like this as secured with 2fa but some of them are scam. So this is not only about security you should also know if the exchanges is licensed exchange and legit. Security is number one needed and 2nd is legitimacy of the exchange.
Since they already made this topic I'm sure the most mention here is Binance which is one of the best exchange for now and for non-KYC hotbit is the best option.
