Can we expect altcoins to reach the success of Bitcoin? and how long would it take? what are success metrics?
As long as bitcoin becomes the benchmark for determining the price and the movement of an altcoin there probably will not be any altcoin that can beat bitcoin success. But, to become the toughest competitor of bitcoin may be a very open opportunity because even in the competitive economy it is indispensable to make comparisons and get the shortcomings of each and be evaluated by developers to make the coin better.
