I don't think It is a good choice to do bounty full time right now. Crypto prices are rather low and some of them almost no prices, I can't imagine how much money in dollars you got every month. Personally, It is hard to get income from bounty only. I make bounty as the additional income, and not make it to be the main income. Basically, crypto is an asset or investment, so it sometimes needs a long time to have ideal price to sell. We need regular income to fulfill our needs every day.
