You and OP have the same mistake - you trade exchange, when you should trade margin.

In trading exchange bots will lose in unregulated market. Only the best bots can benefit where insider information is a common thing.

In margin trading however what you do is extend your overal capital, i.e. by having 10k usd you can make profits of holding 10k and trading 100k (at 10x margin). However of course margin is more dangerous but nevertheless you'll most likely end up with positive in the long run.
