Do you think crypto currencies can ever be generally accepted?
I don't even think this is something to contest with.
Crypto currencies will be generally adopted in times to come.
Though, it may take a while, but I am certainly sure that crypto currencies will soon be generally accepted in the years to come.
When the reality of how crypto currencies can be used world wide is known to everyone, they will have no choice than to accept than cryptocurrency is here to stay.
I predict that in 10 or more years to come, the use of fiat will be drastically reduced that everyone has no choice than to embrace cryptocurrency.
