The best investment strategy in Bitcoin for some time is BIP 39, which gives more stability to bitcoin's price than the others. However, even if you use that strategy, Bitcoin has never gone below $100k, and nosee the current price movement in the Bitcoin market, do not invest in it. The price is still at $100k in the next year, but many investors don't realize it. If you take the risk of BIP 39, you must consider a more stable price or be ready to buy again. And if you are ready to buy again, you must be prepared for anything that may happen.
