Never see a low price and then buy in spite of it. That is one of the most false trade views I've ever known. because there is a certain incident there is a sharp drop in prices. Although the prices of alts are low now, look for other good reasons to buy alts. such as analyzing whether the crowd still paid attention to alts, or did the alts contribute to the past days? If everyone is still interested in Bitcoin, then you should buy, because the demand of alts will be low and it will definitely drop in the future.
