It would be a great decision to invest in altcoins that are oversold at the moment. I like XLM, because the price is pretty silly right now and the coin has a great potential to get into top 3 crypto currencies.
I still can not understand what is the point of investing in cheap altcoins because, in general, the economy is the same, as today, in general, everything depends on the interest in the project as well as on its capitalization.
