Sadly one of my friends have that same feeling. He jumped into cryptocurrencies just to make money and he dropped like 1/3 in dollar value. Now he regretted getting into altcoin markets he seek for bitcoin investments.
very sad if I read your friend story. why do your friends blame cryptocurrency ?
but he just does not have a good base to play in the world of crypto. not inexperienced but all he hoped for was a profit of course he was a fool
