I've been around and watched alot of meme coins come from no where and made the unimaginable happen for some people who were lucky enough to have invested in that coin at its very early stage.
I started investing in meme coins very recently, and the first and only meme coin I am currently invested in is COQ inu, the price have actually risen a bit from the price I bought it, which means, If I were to sell it now, I will make some profit for sure, but then, I've decided to neither sell it, or even take profit, for I believe that COQ will do very well in the coming bull run.
Meme coins investment is very risky, since they usually have no real utility aside from them being speculative tokens, but then, the ROI is always worth the risk if one is lucky to find and invest in one that manages to break out.
