Hi buddy, addiction is a very hard thing to cure, u can't really paper over it with something else, as the price volatility of bitcoin can encourage even more gambling. Ultimately u need to get to the bottom of his addiction, I would openly chat to them and ask how they feel when the win/lose a bet/trade, when they first started betting, why do they think they gamble, what's the end goal of their gambling. If they mainly bet football, then something like fantasy premier league can give the same dopamine hit when they get a good week (but they don't need to waste money). Once u have addressed that, if u do orange pill them properly, then bitcoin becomes euphoric. U ignore the price, u understand the central bank manipulation, the robbing of your time and energy. You see the beauty of el Salvador, not giving 20% of remittances to greet corporates, u see how merchants can bypass the 3-10% fees to MasterCard/visa by using lightning. You see the libertarian side of people escaping war torn countries with a seed phrase. That purposeful enlightenment might help ease the need to gamble. I've seen a lot of people wasting their time and money gambling night and day. Its sad to see and I hope you get your friend orange pilled. When they are ready sign them up to things like like fountain (earning SATs for listening to podcasts), tweetoshi (earning SATs for looking at twitter) and zeebeedee (playing games like bitcoin miner). Hope you get them orange pilled man 😎
