I found that there are fewer and fewer strong dealers now, and there are a lot of rubbish dealers. After a whole year, I found that the real strong dealers are still the North American big brothers behind why and the OraProtocol ecosystem.
But strong dealers usually don’t want to play on the chain before (maybe much better later), so this year there is only why olm 7007. As for how to find strong dealers, I can only say that you can chat with friends in the circle more and then use money to verify. There are too many people pretending to have money now.
