There has recently been a lot of hype about altcoins and how they will grow in the future, how is investing in them optimum for good results. Altcoins like humaniq, LALA World, Wala are my main targets for the portfolio.
Just invest on alts that is already in the market for long time for long term goal. Buy ETH or LTC now and just wait it to back to its value. You can also try to invest on EOS and hold it for a year or more. Some ICOs are also good but I think not for long term.
