nope. zoom in to the hourly chart. bitfinex came back online 2+ hours before that big green candle through $10k.
Even if there was a temporal relationship between these two events, I highly doubt bitcoin's rise was due to what a single exchange was doing. We're not back in the Mt. Gox days anymore.
Let's face it, bitcoin was feeling some bullishness even before it broke through $10k this time, and it would have been a pretty easy prediction to say that it was headed there. It was hovering in the $9800 range for a couple of days if any of you recall. As to the real reason? I say "who cares" and also it's not something that can be pinpointed to any one event. There hasn't been any major news, rumor, or anything else that would account for its rise. I think bitcoin had been beaten down enough over the past two years that investors are starting to muster the courage to get back into the market.
Lots of buying=price increase, and to me it's as simple as that.
