Are you still buying second-tier altcoins? Yesterday, ACT plummeted by 50%, and today MASK dropped by 50%. You thought you had caught the bottom, but it might just be the market manipulators luring you in to raise the price; the trap has already been set.
Don't rush; the crash is part of the market rotation process. I hope your coins won't become the next target.
Still, the same advice: if you want to participate now, the best strategy is to keep large funds in cash and let small funds play with low-quality coins. This can reduce trial and error costs while allowing you to seize potential opportunities at any time.
