OP posted a link to his bets in the recent 3 months and he wins less than 50% of the bets he places. Pretty underwhelming for somebody that supposedly has so much insight.
Win rate means absolutely nothing in profitable betting, his average odds are 2.74 of course he is going to be winning below 50%.
His avg return on investment is 10.8% which is very impressive, but his sample is small with only 330 bets and there's still no answer to why he needs staking.
