90% of this type of garbage coins like $DYDX are just following the market rebound and doubling a bit, provided that Ethereum can break new highs later. In the crypto world, there are at least a few hundred thousand such garbage coins, and they can at most double a bit during a rebound. If they don't sell off later and the market experiences a weekly correction, most of the altcoins will hit new lows. If we directly enter a bear market, they will be worth zero.
