although SUI might seem so great despite recent pump, speaking from the ecosystem of SUI itself mostly it's still pretty bad if i'm being honest, so many project are still new and not as good as its competition like solana.
I honestly don't know why SUI just keep going up though, rarely heard about hype inside the ecosystem yet the demand keep increasing as if something is going on.

personally I wouldn't buy, the risk is too high already for small profit because price already $5 definitely wait for retracement like everyone said.
