Hello Pele, the crypto currency has been declared as a legal currency so there is no doubt that there will be any illegal money that would be accounted for or blamed as black money. It is really a fact that Bitcoin will be as it has be one of the most powerful currencies in the world soon. I understand your point and completely respect your opinion. The currency is ongoing since the start of its invention in 2009, so there is no doubt about any negative point. !! Hope this helps. Lets connect if you wish :) Thank you for your time @pele23
