As of now, the market is highly speculative and does not give much of a leeway to capture undervaluations. Having said that, there are a few projects that might hold some promise:

- Polkadot and  Polkadot markets. Quite a bit of development, solid cripto, no scam (IMO).
- Grin. Lovely privacy an very cheap per unit.

And something called Ice Rock Mining, token ROCK2 (Eth chain). Is quite obscure in general so either is purely an scam or, if the bitcoin mining is actually happening, there is a huge potential for earnings at current prices.
