We often use Fundamental Analysis to answer the question What to Buy/Sell? Or Should we buy/sell that product or not?
And use Technical Analysis (looking at the chart) to decide to buy/sell at What Price?
In addition, fundamental analysis of external macro factors helps you decide WHEN to act.
In financial investment, answering the question "When?" is more important than the question "How much?"
P/s: In the last wave, I had time to let you guys get on the boat to catch the bottom of the spot when BTC reached the 68-69 zone and reminded you guys to protect your profits (depending on each person's position) when BTC reached the 9x price zone when the entire market was still growing very hot.
In investment, the most difficult thing is choosing the time to buy and the time to sell. Success or failure depends on the timing.
