DeFi projects, good low cap alt coins, its not too late, but the markets are starting to go crazy so just buy and hold. Cheap good ones to get in still are
ZIL / DIGI / Vechain / REN / DNT / HEDERA / ADA / XLM Stellar and Quantstamp ( The leaders in block chain security )
these are still cheap and have major room for growth, of course there are more but to keep it simple for some cheap ones, there you go.
Each one of them has amazing potential and Awesome tech behind it
