I won't lie shitcoins brings the biggest profits if you know your way around them, the way is buy at very early stage of release and wait for just weeks the higher the volume grows the faster your money climbs up so just find an exit point.
I think that buying shitcoin on early stage or at any other stage does not matter a lot. Because everyone that has bought a meme coin straight after its topic appears here in ANN, would be rich. The idea of earning through meme coins is to hit the trend. If you are lucky, the meme coin you have bought will rise huge demand. The difficulty is to know what will be in trend tomorrow or in future. With meme, that is something impossible to predict.
