Hi guys,
Do you know if exist something like ebay, but based on crypto?
You may need to be more explicit. Do you have an idea you wish to put up and just trying to survey if such idea has already been implemented? If this is the case, if you come out plainly, two things will happen. You will get better recommendation And or you will get partners who may be willing to work with you. What exactly do you want or has that been answered already?
He already mentioned that he is not only interested in buying, but also in selling. Although other members have recommended different platforms here, when it comes to selling I'm not sure where he could go, except the marketplace in this forum, like it was already said. Maybe not a really great volume of target buyers, but who knows.
About the buying experience, on the other hand, I only used purse.io once so not really sure, but I can say that bitrefill always works fine.
