The price of Bitcoin is determined by a combination of supply and demand, as well as scarcity.The more people that join the network, the bigger the economy will continue to grow. Bitcoin getting mainstream attention is the best thing in the world because it allows people to see it, speculate on it, and potentially adopt it. The real gem behind Bitcoin is the blockchain, that is the driving force behind its technology!
Another major factor that pushes people toward Bitcoin is the fact that it is a decentralized form of payment, running from peer to peer. We live in a time where people are becoming less and less trusting of our governing bodies, so cryptocurrencies like Bitcoin play a heavy role in the alternative factor. You're now at the Fulcrum of the revolution, in this age that we're in, we will slowly but surely see many changes, not just in economy, but within society itself.
