For crypto bookmakers, I suggest using nitrogensports and Sportsbet. For the best odds and high-level promotions, 5dimes looks as a good alternative. All opinions are subjective and you should make your own research before gambling with big funds. For the long term profitable users, Pinnacle will be your best shot. Pinnacle never limits the players and they have to accept BTC as a payment method AFAIK.
Sportsbet.io has small limits.
Nitrogensports is banned my country's IP so have to use VPN. Kinda annoying.
Pinnacle is shit, they used to be good.
5dimes is meh, never really liked them.
Looking for alternatives, the more the better. High limits are a priority.
