Great thread. The best bots for crypto in my opinion would be the ones focusing on arbitrage opportunities which are so many right now and not saturated at all even in major exchanges like Bittrex and Binance.
There is no consensus view that algorithmic trading can outperform discretionary decisions in any asset class, unless it's doing high frequency trading, reacting faster than human ability... so I would be very curious to find out what your results are using any of the bots mentioned, especially in arb trading.
