I think this time, all coin prices are so close to the dip. We can buy amount of coins to speculate. But, the invested fund have to be in risk. Because we don't know when the market is raising again.
I do not think for a long time that prices will recover and rise again, it is important now to buy as many altcoins as possible to prepare for that. Do not be too pessimistic about the low price, consider the future is essential to make money

actually I also want to do that and invest with all my capital at this cheap price, but unfortunately my assets have been trapped when the purchase price is expensive, and now I can only HODL
