Well, I think that what you are stating really does make sense and is sounding really good to everyone's ears. But the thing is, you forgot to mention the people that invest more than they can afford to lose just because they want to have savings plus profits. This is the real problem here because as we all know, the prices of bitcoins really does not stay constant. It can either go massively up or drastically go down. Now imagine a scenario when all of the cryptos are down due to the bearish season and suddenly an emergency comes. Obviously, you will be forced to cut losses and cash out. And the worse part? It would be what if even if you sell all your crypto currency on your portfolio you still won't have enough funds for the emergency? That would obviously be a very big problem. This can also be applied to people who only put money that they can afford to lose. Think about it, if you had a lot of extra and invested it on some crypto rather than putting it on the banks, the same thing can also happen. I think that these are the risks of investing into this industry. Which is why, everyone should really educate themselves to as much as they can about this industry to avoid shitty situations.
