As with most crypto casinos nowadays, I miss something unique in Bets.io, something of their own that would set them apart from other casinos.
They have one thing though: they accept over 390 different cryptos as deposits, which I guess is interesting since even the pioneers in this area (BC.Game or Betfury, for example) don’t cover as many. Although it’s true that Bets.io has this only for deposits and not for withdrawals. Would you deposit in a casino that accepts your token as a deposit but not a withdrawal?
Other than that they are a ‘classic’ crypto-only casino. My personal opinion is that they might be worth trying out, although I wouldn’t list them among the top crypto casinos.
Here's the whole review.
