as long as blockchain networks can not be broken, it will not happen
traditional investment methods are safer buy doesnt make 20x-100x
it depends on what you invest in crypto
i personelly can invest up to 5 years of my saving into crypto.
if that money makes 20x then i will be retired, if i lose all the money, i work for extra 5 years
Buterin is just an honest to itself. Traditional assets still good to invest at, specially you are conservative kind of investors.
But if you need a quick ROI and huge gain then cryptocurrency is a good choice as long you know how to play it.
