I used to be most afraid of the platform being insecure, and that I couldn't withdraw my money after putting it in. Later, I used WEEX, and at first, I was also very cautious, but the more I used it, the more at ease I became. Most of their users' assets are stored in cold wallets, and they also use technology like sharded private keys and multi-location backups (it's said to be an upgraded version of multi-signature? Anyway, it’s very advanced). Withdrawals also have limits, which basically eliminates the possibility of theft. They use Amazon and Hong Kong financial-grade networks for their servers, and the entire transmission process is encrypted. To be honest, it’s even safer than I imagined.
