I think Invest only in established altcoin that have a trusted dev team. A few tips might be the ones in my signature.
But established altcoins are too stable now, they dont jump in price, investing in them won´t bring you a lot of money and it´s not sure that they will stay at the same price, maybe investing in some other altcoins that are not so stable might be a good idea too.
But you can invest alot of money in them, and make lets say 20-30% ROI /year.
Way better than a bank account savings interest, plus it has the possibility to jump higher too anytime.
Not to mention that you can earn more of it by mining.
