Bitcoin and crypto only provide opportunities to a few people who are somewhat versed in crypto, and have the spare money to begin with. It's not like a few people who have increased their net worth and purchasing power would be enough to lift a country's economy up, it has to be more than that.
Can't speak for others, but I have made a decent amount the past few years, which I've set aside and reinvest it when possible. In conclusion, cryptocurrency has helped me maintain some kind financial freedom.
