There are many proposals for cryptocurrencies, such as Monero. The point is, theres already a Bitcoin SE. Shouldn’t the other cryptocurrencies be combined?
By the way, there are hundreds and hundreds of different alt coins, and more in the future. If we have 100 SE sites on Cryptocurrency, shouldn’t they just be combined?
EDIT: Yup, heres even more proof. List of SE cryptocurrency sites in BETA or RELEASED:
and many others. At this rate, theres going to be dozens of SE sites dedicated to Cryptocurrency...
EDIT 2: Have you even seen the hundreds of ‘blockchain’ suggestions on here? There’s so many propalsals just on this one topic...
