As you know, customers will always choose an exchange with good liquidity that can offer a narrower spread. The cryptocurrency market attracts not only new members, but also scammers. Even the largest exchanges, like Binance or Poloniex, aren't always able to resist hacking attacks. Therefore, owners of cryptocurrency exchanges should constantly improve the security of their apps by methods like two-factor authentication, cold and hot wallets, database encryption, anti-phishing features, etc. Keep in mind to test your application. The scope of testing should cover an assessment of overall system performance, functionality, speed, and security. Also, collect user feedback and make necessary improvements to ensure smooth operation and improve the UX. In addition to preparing for the launch and gaining an initial customer base, you should implement processes that will improve user loyalty. For example, you can provide ongoing customer support and take care of your asset management strategy.
