The current moment in the market is dull and depressing, with many uncertainties. BTC will not deliver much more upside; forget about 150k. In two or three weeks, it's only going to go down, and many altcoins have already not survived the crypto winter, and the rest will die from now on. Don't keep buying a bunch of junk thinking it's cheap; the truth is that it's already dead.
And exchanges list memes not because they are good or because they have fundamentals, but because they attract many fools to trade, paying fees that generate enormous revenue for them.
