Bots should not be used without knowing what they actually do. To use them effectively you should already have a very good understanding of the markets and when this is the case, you would probably want to write your own bot and not really share it with anyone.

If a bot currently works really well with the current market state and everyone starts using the same trading logic, it could affect the markets negatively and can cause even bigger losses for you than manual trading.

If a bot's trading logic does show a profit with past data, it also does not necessarily mean that it would cater for new types of changes in the markets in the future.

I would suggest you stick to manual trading and try to avoid high-risk coins until you get the hang of it.
