That last few bets looked like some martingale strategy then an all in play at the end, not saying anything bad but it could've gone either way. I agree on the live bet part it's really great if you can take advantage of the odds swing when it's available but as what tyki said it takes a lot of effort to monitor the match closely so you could get the best odds possible.
After that advices and advantages, i would also like to make an advice to Sportsbet.io as well from my perspective that could enhance their services even further:
1) From my sight, promotions doesnt seem attractive, i have staked more than 300 ETH in general and havent got single dime or VIP service as promotion since they only offer loss cashbacks. I know that people might say "man you have won more than a BTC, dont push your luck" but the thing is that i think VIP services and promotional offers should be on a stake amount basis, not loss amount.
Their VIP seems more focused on the casino that's why they don't have one yet. Maybe they'll introduce one in the future but it would come at a cost of lowering their odds which a lot of people might not like.
