Lol, 20k overnight that's so beyond our limitation lol. We can't really attain 20k overnight. 9k to 20k? I think this will not be the case of bitcoin. I think the pullback of price is connected to what happened to myetherwallet. So the chance of pullback is 100%.
I don't think it's solely attributable to that issue, it's also just a result of an extended period of growth and reaching a level of large resistance. Is there any official word yet on compromised funds from myetherwallet?
