I obviously think that at any point in time anyone could decide to invest in crypto because the prices could further swing either ways at any time except you are buying for "Holding" that is, on the long-term. For example, the price of altcoin "A" sold for as low as $2, probably from it initial market prices of $5, in the last 24hours, colud further drop to $.09 after the next day. I believe everyone actually has his or her strategy on crypto investing, and not necessarily buyiny when prices are certainly low at some points in time in my opinion.
