I’ve had people tell me both yes and no. I tried to find it on eBay but no luck. Is there some secret key words or something to find it ? Please let me know . Thanks
And why would you buy bitcoin on eBay? There are specialized platforms where you can do this. Such as centralized cryptoexchangers, like Binance. Not the best option, but definitely better than eBay.

The solution to the issue of purchasing bitcoin using Bisq or BestChange is, of course, much better in view of the absence of KYC (in some cases).
Just try to find a legal way to buy Bitcoin. You may use P2P services to buy Bitcoin with your local fiat.
How can something that is still outside the legality be purchased in a legal way?

It’s better to say, the most convenient and easiest way to buy bitcoin. And it’s important, safe, because there are still plenty of scammers.
If OP is looking for bitcoin to buy on eBay, then I doubt that he should make P2P purchases, especially for fiat. No matter how they tricked him there.
