Personally, i would go with the cryptos which are less way than a dollar per token/coin.
Incase there is an up trend like one that happened in late 2017, be very certain to make thousands to millions of dollars depending on your initial investment. I would mostly look at coins/Tokens that haven't yet shown their full potential since they entered the market during the bearish period and include a few old coins too.
The new entrants would include:
- Pundi
- TRON
- VeChain
- Zilliqa
- Holo Token

The old players would be

- NEM
- XRP
- Cardano
