Yes good point- Volume is a very good indicator.
Those who want to know- I would be careful trading shitcoins because they are easily manipulated by Pump N Dumps. If you want to use Gunbot on shitcoins, I would changes settings to be more cautious, higher buy level1 on Stepgain or increase minimum prices to analyse (last one Gunthar's advice)
Yep. Personally I set it so that it uses no more than 5% each trade, some people who trade manually say never use more than that which I think is a good measure.
A combination of automatic trading and manual trading often tends to be much better than just doing one of each.
My advice is to pick altcoins that are quite stable against btc or eth. don't pick a tanking/dying coin.
High volume usually has the highest importance.
