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.
If you are doing some investment and you get your ROI back and your profit BACK don't invest on second time or don't reinvested it you're just giving a chance of scammer scammed your bitcoin and signature campaign is really good source income every month or per wwek depends.
There is nothing wrong with reinvesting if the business you are investing is a legit business; casinos are good example of this if you invest in an established casino you are bound to get 1% to 2% on average per month which is great if we compare it with the investment that you can get in a bank.
That's right if you are earning good profits from certain investment then you will surely reinvest at same place as you will start gaining trust on it and you will never experiment by investing at some other place.
