I would go with sth like ADA (Cardano) or XLM (Stellar) - they are cheap but top 20 and good teams. Then I would try to sell hi and rebuy low or jump into another coin.
remember that it doesnt really matter if you buy 0.0001 expensive coin for $50 and it goes 50% up or you buy 5000 cheap coins for $50 and they go up 50% - you still earned 50% (25$)
good luck!
