I thought ETH was a steal yesterday and got it for:

Today I see my investment go down almost 20%:

Well, I indeed considered the scenario of ETH going way lower as a very possible one,because come on, we have all heard about it's scalability issue, possible move to proof of stake and etc.

Indeed, many people are pulling their money out of it. But for the mid term the ETH is not going anywhere. Once the issues are sorted and once the Bitcoin is stabel as well, we'll see all go up. Especially concerning how much media coverage cryptos are getting today, more and more people will invest their Fiat money into them.
