Heck, everyone who got in within the last 4 weeks and didn't ride the wave is probably in the red right now. I'm one of em. I'm ok with that. Things will bounce back and times to buy are ripe. It should culminate into a huge btc drop before fork.
It's only a loss if you panic and sell! While that may be wise in some cases, i feel that btc and ether will be juuuuust fine. I hope so!!!
