Crypto currencies became very popular in recent time.

Looking at the openSUSE Build Service, only a very limited set of packages is
present in projects and openSUSE itself.

But Markus Reckwerth (marec2000) maintains a large set of these packages in
https://build.opensuse.org/project/show/home:marec2000:cryptocoins

I would like to propose:

- Create a dedicated repository for crypto currencies. I can imagine name
"coins", "cryptocoins", "cryptocurrencies", or eventually more generic
repository "crypto" or "cryptography".

- Move home:marec2000:cryptocoins there.

- Move devel project of network/bitcoin (and eventually other packages) there.

It will get more popularity for this repo and also allow to get all these
packages directly to the openSUSE distribution.
