The proliferation of crypto-currencies is certainly not good for the system. It is now worsened by the fact of the proliferation of bitcoin itself through these numerous forks coming out of bitcoin.
In the long term interest of the system, bitcoin should steer clear of the crypto-currencies proliferation. It is no good at all, in my humble opinion.
Thanks @exyle for this great post. In a matter of days, we shall see how the Bitcoin Gold turns out.
