Further growth can bring lot of money the owner. It's evolution of cryptocurrency now. Why not invest right now?
I think so. The price of altcoin relative to bitcoin is low. It is better to buy some good ones.
When the price of bitcoin going down, some altcoins price will increase including Ethereum. That's why before the bitcoin price going down you must buy Ethereum now and i think today is a good time to buy Ethereum because i can feel the bitcoin price will going down soon and ETH price will go up.
