OpenDax is good but this doesn't support all altcoins

There's no single exchange which support all altcoin? Surely you know there are thousand coin & tokens out there, where many of those are barely alive.

If you don't want that suggestion above then there are many open-source crypto exchanges I gathered some of them a year ago and here's my list below.

Check this one below the design looks the same as Binance but in the Chinese version, you can maybe edit the language to English.

Other open-source crypto exchanges below.

- https://github.com/wlox/wlox
- https://github.com/3s3s/opentrade

These one don't know if safe or not but you can check the source if is safe or not

- https://github.com/GMX9/Crypto-Exchange-PHP
- https://github.com/huokedu/Open-Source-Cryptocurrency-Exchange

You mention 5 open source crypto exchange, but mention that you don't know 2 of them are safe or not. By any chance, do you audit the code of those 3 open source crypto exchange?
