If you have got the funds and are looking for long-term investment then it wouldn't be a bad idea to buy Ethereum and hold it for long term, as the price of Ethereum is very low now.
I would like to say that it is still a very good time to buy Etherium. In fact currently Etherium is trading too much low, the price is currently too much attractive, therefore i think that investing money in Etherium in current time is really too much good. It can surely give us a very good profit. I think that the most important is to hold our etherium and even some other altcoin which also have expected to increase too much their price.
