no it is not. if one has the money to invest now, i did advice you do that immediately as bitcoin has so much potential and in few years to come the world will see all of its potential
It is not too late to invest, actually, today is the right time to invest because you will jot be required to have a large amount of money to have it. For me, bitcoin can be compared in bubble.
Yes, I agree, Bitcoin will pump soon, Its the half of the year 2018, They will still hope on that.
