I've been using betcoin for nearly 5 years and have had an overall great experience. The sportsbooks has a lot of positives going for it including:

Promotions - Betcoin offers a variety of good promos throughout the years. My favorite promotions that they have run were for the World Cup, March Madness, and NFL. The NFL handicapper in particular is a top notch promo that runs every week during the NFL season. The prizepool is 25k for the entire season with 1k a week. There are usually less than 40 entries and the top 3 get paid out. I've won a few times and placed in the top 3. Overall it is a great promotion and easy to enter. March Madness is also a great one where there is a similar prizepool with a similar number of users. Again, a great promo.

Sportsbook - The sportsbook offers a variety of matches and has a ridiculously good amount of odds offered. In particular it is great for tennis offering more matches and odds than any other site I could find. If you enjoy betting on tennis, betcoin is a great site.

Deposits/Withdrawals - Deposits and withdrawals are very quick. Most withdrawals are processed within an hour. There are numerous different cryptocurrencies that you can use.

Support - There is both a ticket system and live support. I've had good experience with the staff and the for the most part they are very reasonable.

Bonuses - The bonuses here are very good including a monthly bonus. They are very fair and generous. There also is a nice betback/lossback system to add to your balance when you are down on your luck

Overall, I've used Betcoin for a long time and will continue to do so. You'll have a good experience here
