Ethereum has proved that is a decent coin. His price has raised more then double in the last weeks. I believe that it is the next Bitcoin! I suggest you to buy some and save it for at least 6 months
Yes there is no doubt about this. I think still are some other altcoin with good potential.
I mostly invest my money in trading such coins, as it is always expected that the price of these altcoin will increase specially when the price of bitcoin will stop increasing and will remain as stable currency. For this I have already in mind some currencies to be trade.
investment in Ethereum is not a bad decision. because etereum still has good potential and its price can crease more and more. as some people think that its price is already trading so high but to me think still it has potential to increase more and more.
