I don't understand why all those "instant" exchanges come with these lies:
How does Zat work?
You hold the private keys.
Why should I trust you?
We do not ask or require you to store cryptocurrency with us in-order to use our services. While we are relatively new, we take pride in keeping our services secure and as seamless as possible.
Reasons to trust Zat:
No required deposit of storage to exchange.
This is a lie and you know it all too well.
The moment I choose to make an exchange I have to send coins out of my address and into yours before I see the other coins in mine, so I have to trust you, I have relinquished all control over all those coins sent so I'm basically helpless if you decide that you won't honor that transfer.
Instant exchanges like this are still centralized and it's the same thing as doing an exchange on Binance, you just don't have to open an account and pass a KYC.
You still have to trust Binance or Zat to approve your withdrawal.
