Btw, according to the email I received, it's stated there that I can take part in the 2 free bets promo (for Arsenal partnership)
Place any Pre-live, Live, Single or Multi bet of at least 1 mBTC with minimum odds of 1.50. The bet must settle by Friday 23:59 GMT to qualify.
I wanted to ask if I can opt-in to participate in the promo using other cryptos apart from mBTC, like ETH or TRX?
Yes you can bet with altcoins and qualify for the promo. These are the amounts posted in the terms and conditions of the promo.
