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.


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 think for now peer to peer bitcoin transactions are often done by many people, especially ordinary people. For example, when people buy bitcoin through ATM machines using paper money and then use their bitcoin to pay for food or coffee to the merchant it can be said that people have been doing peer to peer bitcoin transactions.

Governments can only intervene when there is Fiat involved and that is why they are targeting the on ramp and off ramp at exchanges with their KYC/AML regulations. People will always be able to sell and buy bitcoins on a face to face basis, but centralized exchanges just broaden the available buyer and sellers market. 

The decentralized exchanges has also made it more difficult for governments to stop people from trading bitcoins.  The technology will always stay one or two steps in front of government actions. 

But crypto currency field is decentralized so no one can control it if it tries to kill the banks and fiat money because it is all in the hands of the crypto currency users,if everyone using the crypto currencies in the future then the peer to peer transaction will become possible and that is what the main reason for the invention of the crypto currencies then we can feel the freedom of using our money on our own.

People use exchanges because they need to sell their earned Bitcoins to get fiat for spending or to buy Bitcoins with fiat that they earn. So, a more correct question would be "when will we be able to go 100% Bitcoin"? Right now it's not realistic to live on Bitcoin only, you'd have to take long trips to even buy all the needed groceries, and sometimes it would be just impossible to buy something with BTC.

In the future Bitcoin adoption should be higher, so in some parts of the world people will have a chance to use only it, but I personally don't think that it will be like that globally, especially if some countries will keep restricting its use.

Cryptocurrency has always been a threat to the usual currency and this is the reason that banks and governments of some countries are against it. They are trying to suppress crypto by imposing "bans" on it. But I think this will not help much if people decides to accept it.

Isn't it already happening with trusted members in marketplace section here in this forum(without escrow)?
IMO they can use bitcoin and blockchain tech to their own advantage and they don't need to stop it in order to adopt its tech. Direct peer-to-peer transactions worldwide would be possible in the future thanks to bitcoin, but there will always be someone who prefers transactions mediated by a third party rather than p2p, and for this reason, I think banks and crypto can coexist.

P2P transacion is possible even there is a lot of projects are developing platforms for P2P transactions

Do not compare Bitcoin with an electric car case...! an Electric car is a centralized project and everything centralized can easily be killed by the government through regulation while Bitcoin is a decentralized currency that is not controlled by any company or institution

it's starting to be regulated, but generally speaking the ban is not really threat. I'm sure that the only real competitor of cryptocurrencies are crypticurrencies themselves.
