We know for a fact that we have manipulative traders on Bitfinex, that wash traded over $60 million USD of margin positions on July 27th though July 31st.
If you truly believe they aren’t wash trading the long positions with what in my opinion, is fake money, I have some Bitcoin in the Genesis block I’d like to sell you.

Per terms of agreement for Tether US users are not allowed to use or hold Tether. Interpret that for yourself.
Day-trading requires a steady supply of adult-sized diapers, especially when bots can see any order you place and wash trade you into oblivion.
Oh, and for anyone who's thinking of trading on margin, just don't. They can place a single wash trade (Placing two orders on an exchange to catch their own bid, illegal in regulated markets, allowed on many crypto exchanges) and blow your account the hell up.
Good luck out there, the waters are rough.
