As for the title, Direct peer-to-peer transactions are possible. And a third party isn't always needed to sell Bitcoin. There are decentralized exchanges and in personal Local Bitcoin trades.
So I'm just wondering if bitcoin or cryptocurrency should be the future form of our money and it will continue to the future because it has a threat to the banks or it will be stopped again by our own governments of the world just like they stopped the developement of electric cars back when it was first introduced in the market because it was a threat for the oil companies?
Bitcoin is a threat and it always has been a threat to them. They already know this. The thing is, they cant stop Bitcoin. Because of its decentralized nature, it is extremely difficult to stop it. Even if they make laws against it, it would be extremely difficult to enforce those laws due to the anonymous and peer to peer nature of the network. Bitcoin truly is an elegant and beautiful solution/alternative to the fiat system.
I agree. That's why bitcoin is always the topic in medias such as exploiting its negative sides, its risks, what would be the future if bitcoin keeps up to the pace, and the like. However, no one knows what will happen in the future.
