There are still altcoins that are profitable but you have to make a proper research not just invest blindly. I have made a profit investing in lisk because like wise investor they made a research of a project prior to risking your money, right now still waiting for the actual price of waves launch in trading.
Indeed. There are some alt coins that might be worth the investment. It is always advised to make a research before investing anything, but if done right you could make double or triple your investment in no time. I have invested in Lisk as well, and I would say that it has been very profitable for me making me earn double of what I've invested initially. Usually, when you are an early investor (which means taking up some ICO coins) you will end up benefiting from the coins prices once it is released into the market. But still, there have been some ICOs that turned out to become scams. So the best advice would be to never invest money you can't afford to lose.
