For the love of god, do some research on Bitcoin before you spew nonsense. You can't regulate Cryptocurrencies, it's decentralized! That's what makes it so awesome, it can't be controlled by any governments. In order to do so, you need at least 40% of the computing power which is pretty much impossible. The fact you referred to it as a pyramid scheme leads me to believe you don't know what an actual pyramid scheme is. How can you get scammed with crypto, I'd be curious how that works.. Governments have tried to regulate file sharing, look at how well that went, same thing with bitcoin being p2p.
Please take 10minutes out of your day and learn about the blockchain and how it's going to revolutionize currency. You don't need to be an econ major or a technical background to understand the blockchain.

Bitcoin has a finite supply of 21 million coins, the last one will be mined in 2140. This means it's here to stay and isn't going away anytime soon.
