I also used both Binance and Kucoin, of course very well. I would like to introduce another trading platform, Bitstamp.net
Bitstamp.net provides customers with easy-to-use, fast and convenient transaction support. The safety of the Bitstamp platform is very high due to the combination of the best security methods with MultiSig technology for hot wallet, cold storage is fully guaranteed. In which more than 98% of the customer's BTC is kept in safe cold storage. In addition, Bitstamp has other security features, such as two-factor authentication and email confirmation, to enhance the security of your account.
Bitstamp's CEO, Nejc KodriÄ, is known to be a member of the Bitcoin community and the company was created for the purpose of developing Bitcoin, including enhancing account security.
