In crypto currency investing is not that hard to understand but in ICO be careful on it. the assurance of payback or the return of investment is only done in the end of ICO whether it will success or not.
altcoins like LITECOINS and ETHEREUM is best coins that I will recomend to buy and hold. the price now is unstable and ETH is speculated that be 100k USD in the year 2018 and as of now the price is 700 USD , Litecoin also from the dead sleeping and now bumping up again.
