using third party services, but once you use these services, your almost FREE transactions ... turns into "expensive" transactions. I converted
some Bitcoins to fiat today, and I had to use an exchange... They charged me 2% for that privilege. We need to make direct transactions,
without third party services.
This is actually just starting to occur now. While it still is a bit complex, the Omni platform allows you to trade, without ANY exchange, USD for Bitcoin - and a whole bunch of other crypto tokens. This is all done on the BITCOIN blockchain. No bullshit blockchain here. Most importantly, there is NO EXCHANGER. There is just a buyer and a seller. There is NO SPREAD!!! The buying price is the selling price!!! While it is going to take a few years to get popular and efficient with liquidity, it is working today. You really can trade 770 USD for 1 Bitcoin with no fee. With a little time, this system will be HUGE. And it will ruin those greedy assholes at CoinSource as nobody will ever give them even $5.6 let alone $56 dollars for a trade.
Technically, the USD is the crypto version of USD - that is Tether USD. But, nevertheless, you could easily get 1:1 tether:fiat USD from some sources.
Decentralized trading is in its infancy, but coming to a blockchain near you very soon.
