eXch almost always has zero XMR reserves
You sir are a liar troll and you are not telling the truth.
I can see monero is available now on eXch and I have seen it on many other decentralized exchanges and p2p trading services.
eXch reserves:
16-March-2025: 0 XMR
17-March-2025: 0 XMR
18-March-2025: 0 XMR
19-March-2025: 0 XMR
20-March-2025: 0 XMR
... now there are some 245 XMR ... hooray ...
Kucoin - if you want to buy 10k XMR in a day, you need to buy the entire order book and it would cost three times as much + KYC
