Bear whales have done shit like try to push prices down as low as possible to accumulate for eons on Bitstamp. Nobody knows what the "market value" of Bitcoin really is. The only certain thing is that after people who have pushed down the price to accumulate have finished loading up the truck, they will then reverse course and raise it.
Since 75% of coins have already been mined, there's not a whole lot of reason for bear whales to exist anymore, so now the price goes up. Maybe it's not rising. Maybe the market value of Bitcoin was actally several orders of magnitude higher than the price was and now people are letting it go there.
It's possible for it to go up an entire order of magnitude ($300 --> $3000) before the sell pressure really gets heavy enough to stop it for a while.
yes is a dumb question, but also I have see in 2013 in the same period the price "PUMP" very quickly as we know.
every time there is a rising (or price crash) every body ask why! It's normal in the human behaviour try to explain every aspect of their life.
But they don't.
