1. Satoshimine - I am lucky in this site always won. He he.
2. Bustabit - This site is for long run profit. You need to have 0.1 bitcoin or more to get profit on this site or else you will lost.
3. Fortunejack - Same as number two you need to have atleast 0.1 bitcoin funds to get win of this site.
Is there anything like that? Get your profit based on how much bankroll you have. I dont think that make any sense though, sinc e bankroll have nothing to do with your profit because what you really need is some luck not huge bankroll. Anyway for me bitvest and moneypot apps is for sure because every simple thing is good
