I will say now is the best way to invest into altcoin and wait for it after a long period of time and to be an investor you don't need to take time on anything you want to do just jump to it immediately.
Yes, currently the market is still red and the majority of altcoin prices are cheap, so it is a good opportunity to buy. In a hurry, I don't think it should be done, research needs to be done first to determine the most appropriate coin for investment.
