Despite Bitcoin's (BTC) steep rally in November, the price is consolidating above $15,000 as on-chain analyst, Willy Woo says a blow-off top is unlikely for three main reasons. The three factors are the growing outflow of funds from exchanges, increase in “HODLers,” and data showing that investors already took profit.
Don't forget that Willy is a long time Bitcoin bull. He said it himself that he tends to be bullish with his predictions. It's common for analysts who own bitcoins and those who in the past made a lot of money holding it.
The main reason why price went up is supply and demand. I don't believe there was deliberate pumping taking place. If there was any, we can blame Tether 
The market demand and supply play a huge role in the market surge in price but not the main reason for the current market surge/traffic because block halving also played an important role either. Mind you, it (block halving) was implemented for inflation control.
