One of the basic concepts in the stock market/crypto market is to buy at red, sell at green. As we see the market right now, it is in the bull run, so a high percentage of the currency is at green. So for me, investing or buying coins right now is not a wise and good decision since most of them are increasing their price. This is the time for the hodlers not investors, buying coins right now will lead you to either coming back your capital with no profit or worse, losing the money.
Nevertheless, it all depends on what goals you set for yourself. For example, many were selling bitcoin at 25,000, the whole market was green. As a result, the price rose even higher and then even higher and then even higher. Someone was selling at the level of 50,000, the price was green again, but now it costs almost 65,000. Therefore, it is difficult to unambiguously apply your words to the market; you should always look at the situation.
