I think crypto isn't for everyone, some won't just be able to cope with crypto investment, maybe because they are lazy asses or they need to be elsewhere to make their money? What do you think about this?
That person OP is not lazy, he/she is just another person who has no courage to take risks. And instead of keeping their mouths shut, they always spread fake news and baseless information making other people also afraid.
Anyway, there is no need to listen to such a claim, they know nothing. It is too hard to convince such thinking because what they believe now which is wrong actually has been right for them and they will continue to push their wrong thoughts about cryptocurrency.
