i think bitcoin will continue to be a mega crypto untill litecoin replaces it when facvebook joins the bandwagon and buy and improve litecoin..what do you think guys??
So far, I see no reason and need for bitcoin to be replaced in its leadership by crypto currency. With the advent of a new version of bitcoin, which solves problems with its shortcomings, bitcoin should remain in its leadership for a long time.
As for his future replacement for litecoin, this is hardly possible in the near future. I think that ethereum has more chances for this.
