Agreed , you can bet thats what will happen , governments wont let that slide under their nose , it takes time though . Technically the US government can call the show off by declaring owning a bitcoin as a felony .
And when this crypto space becomes regulated you can bet their will be more advanced and regulated coins out there , if blockchain is the next hot thing then microsoft apple google ... etc will have their own coins , and current coins will cease to exist - almost - .
Keep an eye on tether , its a disaster waiting to happen , most crypto exchanges trade coins against tether not against the $ , tether could be the next ponzi scheme .
