$SUI had a nice run but it is losing momentum.

This doesn't seem like a pump and dump scheme. Sui is bigger than most cryptos to be manipulated easily.

So should we buy sui and catch the train?

Well when I do this, it usually goes down and I have to wait just to brake even so I place buy orders at 20% down on current price and try to get lucky or unlucky if it drops more.

This is a waiting game and to be honest I am still learning it.
