When I start betting, it was a local bookmaker I used and they don't accept deposit in crypto, just in fait which was our local currency via bank app transfer or card debit. I started using crypto casinos and bookies few years ago and I doubt I have spent more than $20 worth of Bitcoin to gamble, the truth is that I prefer to deposit USDt than Bitcoin.
That’s understandable since you only registered in 2022. Back in 2017, it was mostly just Bitcoin being used for gambling, super popular at that time. Then later on, casinos started accepting altcoins, but only major ones like Ethereum. Bitcoin wasn't even that expensive before the 2017 bull run. I think around 2016, it was just $500 or so. So if you're really into gambling and could afford it back then, 1 BTC didn’t feel like a big deal.
