No you can't, that's what I'm saying. When I input the address I wanted to use, they prompted me with some bullshit about Swiss regulations and having to sign a decalaration. They don't even provide any sort of explanation about how you're supposed to sign it (if you're an idiot who is willing to do such a stupid thing). All they say is "If you don't want to sign, use our wallet". So I don't use their wallet, or their app.
Based on what I've seen, the premiums people expect on that platform are even stupider than on Bisq, and any potential savings based on batched transactions are lost, and probably by a large margin.
On Bisq a marker maker pays only one of four transactions involved in a trade. The taker pays for the other 3. That usually works out to be 6-7k sats for a taker.
And still, even on days like today which I am skipping because I consider the sellers are being unreasonable, I could buy as much BTC as I could for as little as a 5% premium, while the average on Peach is closer to 10% over market.
So not only the savings would be lost, but I would be losing big time buying there, in fact.
