As of now I think some people knows about bitcoin or rather most of them knows it but they just don't believe it what is the big effect in our life, the question is do you want 90% of people in the world are using bitcoin? why?
No go. Bitcoin is still not ready for a massive users. If this happened, the blocks will be congested, transactions will be left unconfirmed maybe atleast a week because of the massive users. More debate will come, more tension for the miners and will ending up mining other digital currencies loke Bitcoin Cash.
Yeah, I totally agree. A massive users needed a higher size of blocks in which bitcoin cannot attain now. And for me, practically, I don't want to see all or I can say 90% of people are using bitcoin because opportunist people may take advantage that I believe is almost 30% as counted. And I don't want that to increase through use of bitcoin.
