Investing on alt coins is simply waste of time like if you want to hold the funds for long term investment. For short term for investment you can always choose the trading as your field and then you can go with it.
If there is any clumssy behavior in altcoin you can skip such altcoins and goes to other cryptos.
I wouldn't invest in the coins that were released this year because almost all of them are scamming people left and right.
I think there still good altcoin that launch this year. The only altcoin that i dont want this year is the one who has crowd funding . Starting a bussiness with the need of investors fund is not really a good option for investors, mostly because you dont know how good or bad developers can handle a bussiness. They are always giving an idea but dont know how they will really starting it which is i think is not good start.
