It is really tempting isnt it?. Ethereum is a really good investment today but to put all in your money is not really a good move. They always say invest only what you can afford to lose. But if you can afford to lose your money in case anything worst happens, go for it dude.
I'm sure that even if you invest all your funds in the etherium, then you will not lose anything, because even with time this coin will rise in price. I believe that the efirium is more promising and much more stable, with a good price increase for the promising future.
