Bitcoin bookmakers are still long way from the regular ones. THeir payout rate is bad(same as with plenty of USA bookmakers), their offer isnt wide enough and overall they are not solution for serious bettors.
Let me give you better sight of that:
1) YOu hire a tipster with 16% on softbookmaker(bookie with low limits, wide offer and overall much easier to beat than asians and pinn)
2) Instead of bet365 or whill or bookie like that, you take your local one who has lower payout rate. lets say for equal matches instead of odds 1.952-1.952(that pinn gives), they give 1.85 like in my country

First look tells it all, you lose from your tipsters winnings beacuse of their payoutrate. When you add up to it tipster cost, withdrawal fee,, you realise how much it costs you.

If good bookmakers dont allow your country, find a solution. I had USA partners betting over VPN on EU bookies. It is all matter of effort.
