If you have idle funds, choose to invest in dollar-cost averaging for holding coins; if you don't have that idle money, don't act rashly. Even if the idle funds go to zero, it doesn't hurt. Spend one or two thousand each month on regular investments; if you have the condition, three or five thousand or even thirty or fifty thousand is fine. But it must be idle money. Once the transaction is completed, withdraw immediately. Idle funds fundamentally do not affect your life at all. Not only will you not lose flesh, but successful holding can add color to your life. Long-term investment of idle funds is not about heavy assets entering the market. The possibility of playing and getting increasingly poor is zero. Almost all losses are from short-term traders who need capital turnover. Once their funds are trapped and their psychological defenses are broken, they will cut and run even if it means bleeding. This is commonly called being a "leek" (a victim of market manipulation). The money lost is theirs. Both the stock market and the crypto circle are their graveyards, with very few exceptions.
