At a party dude was telling everyone to invest in btc because it is the future, and it was $14k at the time. I explained that it is very risky and volatile and dude would just ignore whatever I was saying, even though I mined many cryptos, bought btc for 1 penny and had a better understanding of tech than him. 3-4 months later crypto was back to $6k and he never mentions it again with me around lol.
The point is many crypto businesses screwed people over (MtGox). Many people lost fortunes from private wallets due to malware, forgetting pw.
If I pay with a credit card I have level of protection. When I put my money in a bank the money is insured. Crypto is simply too risky as a way of storing money and trading.
