I just started with this project so im not aware about the performance paneities of using string for identifiers in orderbook, trades and currencies but I'd prefer to use UUID.

UUID is just 2 longs, so no dramatic perfromance impact is expected.

So can we move order ids and user ids to uuid or string?

I can create a PR.
