What Is Our Expert Opinion On Monsterwin?
Monsterwin is a newly launched bookie, and testing wasn’t that difficult thanks to the Altenar sportsbook. I was really impressed by the football odds, especially on the greatest tournaments such as the World Cup.
The 98+ payout is more than great, as well as the 95.5% on top leagues in general. At the same time, you can use some really useful features such as auto and partial cash-out and combine multiple bet builders on the same betslip. Moreover, the 13+ languages and their additional language variations (e.g., Chilean Spanish) offer decent localisation levels for players. Also, there are 12+ cryptos for those who prefer anonymity in their payments.
However, some things did not work that well for me. First of all, being licensed by Costa Rica should definitely ring some bells to players. Also, the 92.56% average payout on tennis is not solid at all. Moreover, the withdrawal limits are a bit low, at €20,000 monthly.
All in all, I think Monsterwin did a decent try to create a competitive sportsbook. Nonetheless, there’s a lot of room for improvement.
