I dont see Bitcoin staying as strong as it currently is in the ext 60 days. And that is being generous. Bitcoin value is pretty much determined by the amount of volume its being traded. And now its obvious that that volume is reducing due to many know factors and FUD from governments. That being said, i think that it may not stay very valuable for long.
Eth has had some issues and its a bit of a risk itself to expect sustainability. There are foundational issues from developers.
I seem to have more faith in Litecoin. I may be wrong. But for now, thats what is working for me.
