The only one I regret is buying Numenaire at the top. 1 coin at full price, that is worth maybe 15% of what I paid for it now. Shrug. The rest, i am fine with the up and down swings as I think there's a long term future for a lot of them.

I also have a mining rig that was bringing in almost $30 a day a few weeks ago (down to $15 a day now) plus have solar panels on the roof covering 100% of the electricity cost, so even though things are really poor at the moment, I'm just going to keep slowly accumulating crypto (with my largest stake in Steem, actually) and hodl until things turn around.
