I do have the same POV with the blockchain technology but not with cryptocurrencies but dont get me wrong on this. I do hold some cryptocurrencies but some day, some countries might adopt the blockchain technology and implement their own currency with it. China is definitely going to launch their Digital Yuan somewhere in the future and probably might use some of the blockchain technology

To put it simple, cryptocurrencies might change the world economy but not in a way that we all dreamed of. Most of us in this forum definitely want bitcoin to take off and mass adopted but its probably only blockchain that is going to be adopted by the economy system
