According to Anh's correct technical analysis and fundamental analysis, the bottom had already formed at $15,500 (at that time there was full of bad news about Luna collapsing, top1 3ac fund, defi lending platforms collapsing, FTX scam,... ..)

However, according to the time frame, the deeper the dump is near the halving, the better time for investors with money to hold and wait for $200k to sell.

According to the Psychological Chart, the bottom will form at the end of 2023 and close to the halving in March and April*/2024.
