If you are not sure to buy, just wait for the market recovery. It is not a must to buy on every dump, sometimes we are better to watch or see the possibility of the market trend first. I saw in this forum, many people stated Bitcoin price is likely hard to rise up to $40,000 lately. It is not a good sign to buy a Bitcoin, so better to keep your USD/USDT. Just buy again Bitcoin once the price of Bitcoin can go above $40,000.
Logically there is no problem buying Bitcoin when the price has definitely recovered, and there is no necessity when investing in Bitcoin buy when
it dumps. But based on my experience investing in Bitcoin, the profit generated will be much greater when buying a Bitcoin when it dump.
The most important thing is that we don't buy Bitcoin when the price is at its peak, it will only make us lose. So the conclusion depends on our
respective strategies when investing in Bitcoin, as long as we use money that we can afford to lose it should be safe to invest in Bitcoin.
