The world economy Will change,And currencies will go into electronic savings.The number of investor Is growing every day,as a result ,electronic assets will be valued much more then they are now.so the cryptocurrency market is actively growing ,new companies and infrastructure projects appear.There is no negative effects of cryptocurrency to the country at large,they are just doing it or banned it for their selfish interest,all because they know it is more useful for thee youth than they are. So for me and with all I see when it comes their is no negative effects or so ever at all. Most companies that sell product also accept that mode of payment,so if its bad they won't want to accept it in anyway.
