most of them aren't really at fault. they are just poor newcomers who entered a big market and were suddenly bombarded by a huge wave of advertisement which were promising them riches beyond their wildest dreams so they ended up buying a ton of useless tokens which have been continuously losing value
True. Unfortunately in this case, the biggest lesson for people would be to actually get burned by their investments. The cryptocurrency markets are a hugely unregulated market, hence we really expect a lot of people who have zero idea on investing and research to be putting significant amounts of money in. I think it's a good thing though, as I'm pretty sure a huge number of people actually learned about money, investing, and information security by learning about the crypto markets.
