It is already possible to send bitcoins peer-to-peer. You can send money to friends and relatives in the form of bitcoins but an exchange will always be needed to buy and sell bitcoins because it ensures trust between two parties.
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?
You cannot stop progress. Electric cars are simply uncompetitive with the regular ones so far (let's be honest here). If they were real competition, no oil cartel or whatever would be able to stop them. Regarding cryptocurrencies, we already have "direct" peer-to-peer transactions (for the record, peer-to-peer transactions are direct by definition). All we need is a universal acceptance of cryptocurrencies (at least, major ones like Bitcoin) as a means of payment. Then you would not need to convert your coins into fiat to buy a cup of tea, for example. In that case exchanges will be there only for speculators and their likes.
