We are working on the searchbar. You will be able to check every collection that is in this marketplace.
I read your FAQ, but I don't understand what to do with such a result. Buy or sell?
You must observe the line graph.
Each percentage increase for a specific collection is a signal to sell.
For example, recently, for one collection, the chart has grown by 1800%. Think how much the seller could earn if he tried to sell the NFT at that point.
Each percentage decrease is a good buy signal (probably a good price offer appeared).
The higher the jump percentage the better.
