I just started using Bitsgap, in demo I found that Bittrex is the Exchange with more Crypto Pairs that are most profitable, but their fee in real world is too high for beginners 0.75%.

According to my research, Binance is the Exchange with lowest FEES in the market, 0.1% or less.

So, Why then, Bistgap bots in demo mode Have more daily transactions and levels within Bittrex than Binance? (Which has more market volume).

Also, follow up question, what is the variable that makes a Crypto Pair Profitable?
I tried running simulations with highest daily volume, and biggest % change, I know lateral movement is the sweet spot, but is there a Shorcut or best Tip to find these Pairs?

Also I added a simulation of AAVE/USDT parallel to each other with same settings in Binance and Bittrex, with exactly the same parameters Binancae gives me a result of 5.39% and BIttrex of 1.79%.
The backtest has the 0.1% fee on both, so it is not taking into account the higher bittrex Fee.
Dont you find this odd? Or what may be the cause?

Kind regards.
