look at Ripple its amazing its almost 4 time up in last 20 days
LOL, I just made out shorting it yesterday. Hah
Shorted yesterday @5k then it immediately spiked to 7k. LOL hairy I would have got called at 9.9k then tried to close short @3800 but site would not work and it spiked again shit but luckily it went back down to 3800 for me after that second and third spike. Having over 100% margin is critical!
don't forget XRP is 100% premined! so your playing with fire with that one.
What website do you use to short the coins?
https://poloniex.com
Be very careful of ripple (XRP) the whales were destroying margins a few days ago, I almost got caught when it went from 5k to 7k in a second. IMO is should be around 2k (actually I think that crap is worthless).
