Well after all the post here still gambling is still the fastest way to earn bitcoin . But dont be amazed to the "fastest" way. It is the fastest way also to lose all your btc.
well i guess if you can consider a "small chance " of wining a way to earn money, then you can consider gambling as a way to grow your bitcoin!
but the thing is, you lose more money than you can make overall.
I just say that gambling is still the fastest way to earn bitcoins. But of course dont prioritize it.
