I prefer invest to Ethereum, Ripple, Doge, Stellar and Bitcoin if for long term. but if you want to make a profit quickly, you can go to altcoin which is now successful with the sale of ICO and also has a lot of community. I see there are 2 successful ICOs and after entering the exchanger, the price rises 10x from the ICO price ... I see ETHLend and Utrust are good enough for investment...
