Soon we will have a new cryptocurrency. The MimbleWimble developers are working on it and it will enter the last phase of testing. As you may know, MimbleWimble is a spell from Harry Potter.
Still, there are no plenty of data regarding it, like will it be a sidechain or a new chain, but some info suggests it will be a private cryptocurrency.
At the moment, it will be based on voluntary donations, which only the first step. Despite the fact developer, known as Igno Peverell claims there won’t be ICO, we may be able to see this in the near future.
