What I mean by decent is where you can really see that it is growing and it can give you profit that is enough to be reinvested.
Call me dumb but I really don't know. I'm sorry.
My only source of coins is my signature campaign. I earn about less than 0.1 BTC per month.
Any advice would be much appreciated.
Well, no decent and average amount is here in trading, but as you are earning from signature campaign, so you should trading with your 0.1 BTC, and i believe you can also earn from trading 0.1 bit. Also better is that should use limited amount in trading if you have no experience about it, In first month, may be you can't earn more, but later on you will be started earning from it.
