Everyone who is not involved in cryptocurrencies do not know the benefits of them. Also, most of them make fun of it especially when the price goes down. I will not try to convince anyone about it, they will be convinced when they see my lambo.
Actually people feels insecure about putting in their money in assets they do not have information about, And besides it would be completely irrational to invest in assets that are unknown to them. They rather love to make rational decisions and that is to invest and make money in their traditional assets.
This is the start and people will take time to accept this fact that there is something like cryptocurrency that can enhance the economic activity and is another mean to earn money.
