“You can deposit fiat money into the BTC seller's account, but the BTC seller may not send any Bitcoin in the end.”
You are right and that is why to trade with another user (for example you want to buy and Satoshi wants to sell) then Satoshi sends his bitcoins to the cryptoexchangep2p wallet and when the platform receives the BTC, Satoshi's post is recorded and his post will be seen. reflected on the platform, now, before making the exchange, satoshi and you previously contacted through the watshapp channel cryptoexchangep2p in which the aim is to bring together these people who want to exchange Bitcoin and talk about the topic, what happens if cryptocurrencies they are not released. "This fool already deposited me, I can leave" first, he is not the owner of the private keys and you can report the post so that the moderator (me as founder) reviews your transfer receipt to Satoshi so he can release your BTC and Satoshi will be expelled from the platform

"If you work as a broker, are you not charging any price for your services? How will you keep your platforms up and running? I assume there are costs involved, in addition to the time you spend there."
------------------------------------------------------
I plan to charge a commission when withdrawing your BTC from the platform and only when withdrawing your BTC from the platform (Note that I do not charge you a commission for sale and commission for purchase) but this is in the future, for the moment I do not want to monetize, I want attract people to know this new alternative, and the commission will only be 1 USD

"In fact, exchanges charge very expensive fees for transactions, but that is the cost of running the business... It would be great if all Bitcoin enthusiasts had the possibility to transact only through P2P, so that we could have access at fair prices when buying and selling."
------------------------------------------------------
On the contrary, I think they are overcharging us because it is a new market and there are not many options available. If everything goes well in the future we will say (how stupid we were that the exchange charged us for buying and selling and also overselling us BTC and also buying us the BTC from us at a low price)

"But that's not feasible for most of us, because there are no local people to trade with."
-------------------------------------------------------
That's why I want to unite the community in the cryptocurrency exchange p2p WhatsApp group, give them control, I have the same problem. How am I going to sell my BTC to someone local, if I don't know anyone where I live who has this type of asset? and it pisses me off that's why I believe this
