All in? HELL NO, nobody should go all in, regardless of age. Taking higher risks when younger--that's all well and good. But going all-in on anything crypto is a recipe for bankruptcy. I wouldn't even allocate 20% to crypto. You'd have to be crazy to go even half-in, and I say that as a person who likes bitcoin. A lot. It's just way too risky.
Yeah going all in in crypto may result in many things,Not all cryptocurrency coin will remain as is in the future like what are they right now.
Plus putting aside many things and going all in crypto will affect a persons life totally and may destroy their future so this is not advisable to do
