Remember when the market was rising, when BTC reached a new ATH, didn't you hope that one day it would drop to the current level of 55k to buy?
Now that it's returned to this level, you're scared again.
Remember to make a winning trade. Do not go all-in at this stage, there is a very high possibility that the market will continue to decline. Gradually investing in capital will be a reasonable strategy for this period of many opportunities but also full of challenges.
