Even small investment can make big difference when the time comes. There are different approach in buying a crypto,  There are many who are trying to catch the bottom but honestly it's very difficult since I have seen many altcoins dipped lower than their base price last bear market.  Traders are trying to maximize their profits by buying at a good price point. My take is when I see the price is justifiable like for example the price is on the support line, I would buy partially on it so whether it dipped more or bounced back I would be happy with my decision since I still have funds to buy some since I bought partially.
