No one can really answer this question with all certainty since the market has a mind of its own. I would suggest you take time to investigate any coin that interests you and look for a good entry point to buy.
Let's make it easy mate, try to google about bitcoin halving process, and you'll find out that Bitcoin would be the best coin to invest if you want to get huge profits. For me that is the most productive coin out of all the other cryptocurrency, although there are some coins that are also progressive but bitcoin is once coin that is most assured will grow in the next few years. Good luck mate.
