This pump is most likely deliberately caused by a few folks wanting to hurt Bitcoin
And it will end up as abruptly as it started, and it seems like that it is already on the verge of reversing. After it's done with, people will put their money back in Bitcoin, so the current phase of price consolidation around 1,200 dollars per coin may end soon as well and become a starting point for a launch of the Bitcoin moon rocket, figuratively speaking. We have seen a few weak attempts (in fact, I saw just one, but there may have been more) to move the price substantially below the 1,200 dollar mark, but they all failed
I also speculate that there are people behind the attempt to pull the market price below $1200. It is very evident in some threads here, creating uncertainty to create panic in order for others to sell bitcoin. It may have failed, but I don't think they will stop. Alt-coins have been pump lately (almost the top 5 are currently green), but this will be temporarily, as I believe investors are likely to put their money back in the bitcoin ecosystem.
