The progression in currencies used by sportsbet has been followed from 2016 to 2018 when they first started taking Euros. It's also known that Jetwin keeps balances in many fiat currencies.

Since Sportsbet started with cryptos and had a presence here prior to accepting fiat currencies, their rating was kept up in this thread. Cryptocurrencies are accounting for less and less of sportsbet's business. Because of that, I think it's best to just put them in the fiat class.

There has been plenty of poster input on sportsbet that had a great influence on their rating. Here are some other reasons for their final rating.  https://bitcointalk.org/index.php?topic=717790.3020

1. Margins - The margins (odds) at Sportsbet are very high. It's almost impossible for a player to overcome that type of hold with vanilla lines.

2. Self exclusion - When a player asks for self-exclusion, Sportsbet steers the player towards taking a temporary ban.

3. Areezy - Under no circumstances should a book be able to cancel a futures play. Areezy has given me permission to look into his account. If there is something that is missing, please PM.

4. KYC/AML - There are rare cases where KYC may be required. Sportsbet is heavy handed on KYC and confiscated 21.5 BTC form a player of which 15 BTC was from his deposit.

5. Double spend claims - Sportsbet should wait for 1 confirmation if they are going to confiscate funds for an "accused" double spend attempt.

6. Communication - A PM was sent to all books asking if they banned players from the UK or US. Every book replied within a day except Sportsbet."
