This bitcoin global regulation seems for now to be said as the main condition for being able to use bitcoin for payments or transactions in several countries but actually it doesn't really matter because bitcoin has the purpose of creating a currency that cannot be controlled by anyone.
The general rule of Bitcoin worldwide is essentially unnecessary because it is contrary to the purpose of creating Bitcoin but I think that in order to be able to develop stably the general rules for Bitcoin and cryptocurrency is very necessary. The general rules will be the basis for dealing with fraud cases in this market.
