The majority still doesn't look at the technology but at the volatility of the crypto markets. Until this trend won't turn around I think the world won't be ready enough.
Volatility is the great hindrance to people for not to adapt cryptos in our daily lives. The inflation really kills the people and though cryptos doesn't deflate but it's too volatile to use so they rather choose fiat as it have a fix value. But if we can just deeply think it will just be the same as it always have its domino effect in the market. And the fact that only few people knows and open for this technology so likely this will be a long journey for all of us.
I think the world is not yet ready to embrace crypto currency because of the current situation of it, The people are more focused on improving their country without looking for the possibilities that the crypto can offer, they think that crypto will only be a threat to their government, that's why some other countries are banning it.
