Crypto I recommend investing at the current time which is ETH. In all the cryptos currently available on the market, ETH is the most potential crypto when its technology is used by most ICO projects in creating the token. With such a large network, the future potential of ETH is undeniable, predicting ETH's market cap will overtake BTC for the next 2 years.
All coins that has good value in the previous launch after ico has a good potential to rise for it's price. Although eth has more contracts, but we'll also have to see to it that other sub contracts will be developing good market as well. Be confident on your eth tokens it has greater future soon.
Most of the time i go with eth and btc.For sure they will not disappoint you at all.Although the market price is always unpredictable,still these two coins are in the top positions that are mostly trusted by investors and they both have their own potentials that will grow more in time.
