In my opinion, investing in the most stable altcoins with great potential for rise, is the best investment in crypto these days. I would go for Ethereum, Iota, Smart cash, Golem, Blue protocol.
golem and iota are another good coins to buy and I think these coin can get increase soon. besides ethereum, we have much option coins that we can buy and if we can choose the right coins, I am sure that we can make a profit and who knows, if we can buy underestimate coins, we can make a big profit in the future. many of us still don't know which coins that can increase in the short time and makes us choose randomly but sometimes, if we luck, we can get a profit too.
