Definitely, Definitely, DEFINITELY not too late!
We are at a pretty low stage right now, may even go lower and quite considerably lower too! So there is heaps of money to be made...so long as you pick the right markets of course!

And let's not forget as I often say, we are still so far away from mass adoption. As more peeps become involved, the true crypto coins will come to the fore and this world will be everything it promised!
