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.
we're not in the mt gox days, but there's still a handful of exchanges (bitstamp, coinbase, bitfinex, kraken,
probably binance and huobi) that have a huge influence on price.
i do think there are cases where whales try to pump/dump the market when other big exchanges are down. whales on the downed exchanges can't fight the move, so there is some rationality to it. it's a risky move nonetheless.
in general, i assume market moves are organic. it doesn't serve any purpose to speculate about manipulation.
