No idea what's causing it, but in the spirit of never looking a gift horse in the mouth, I have cashed out. Not going to retire, but silly not to take advantage.
I'd also noticed FoldingCoin (and indeed Curecoin) had been on the move lately.
Probably a wise decision. Not gonna' lie I also sold off a large portion of my stash, which was only a bit over 1.5 million LTBC. Which actually I bought at 30 satoshis a piece to replenish coins I sold earlier on. Managed to catch this spike at 190 which was pretty nice :D
Every now and then a random coin or two on Poloniex gets chosen by the crowd for a massive pump, which sometimes fails but also sometimes succeeds such as this case. Like you noticed, the exact same thing happened to FoldingCoin, completely out of nowhere ridiculous volume and price increases, and not like there has been any announcements or any major project developments or anything. Same with us, nothing is happening really other than we continue to exist. As far as me and @adam can tell this was a totally random event and those of us that cashed out some got lucky. Surprisingly the price is still almost 3X what it was not long ago.
