Here is my strategy, I am expecting 2% per day, starting bank roll = 0.02btc. I will be attaching screen shots of my bets each day.
https://imgur.com/wkDh1Cx2% per day profit is not good at all. If you lose few matches, you will probably end up more in losing, rather than winning. If you can predict sports betting, you should aim for 20-50% profit weekly. You only need to bet on matches in which you are confident about the winner and also you do not need to bet daily.
Sports betting is really more on your knowledge of the particular sport. Better place your bets to those matches that you feel you have high chance of winning and aim for much higher profit. But maybe, the OP is only conservative in his calculations. We really don't know how far is his knowledge to the sports he is betting with.
