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.
Yeah no body can really answer that, but let's make it simple, I think a good altcoin for investment is still Bitcoin and ETH because both of these altc types have good value in the market, but there are many other options that you can analyze in marketcap, you can search and study the program from ICO so that you will not lose. Right mate?
