How can you say it’s promising and that the owner has already profited from it?

That address holds almost $20 million worth of PEPE tokens, but the tokens came from Binance just two days ago. My assumption is that the investor likely bought PEPE tokens from Binance and plans to hold them. However, in terms of profitability, it’s too early to tell.

Looking at the data on CMC, it seems like they bought at the peak.
