Dont think its a scam just Bitcoins blockchain needs sorting out and quickly before people and merchants loose trust in it. If you dont have a decent way to send and recieve coins in the end people will just get fed up with it and turn to Altcoins like Ripple
I do not think it's a scam either. We need to understand that this is just beginning and as for example, apple takes out a test phone and then the complete one, that's all this. BTC was the first to reach the top, among all we can improve it every time
