It went from 500 euro (approx) to 600 euro (approx).
Of course, this volatility is to be expected in bitcoin and does not have to be related to the brexit vote. But still, the timing of this increase did co-inside with it.
I agree that bitcoin's fundamentals (block size increase) needs to be fixed for an increase to really be possible in a sustainable manner.
The comparison I use is the hundreds of small-cap companies I have directly been involved in, as well as the large-cap companies I invest in.
I've never experience trading patterns and price increases like this besides when there is malicious trading going on.
Yesterday, I asked my guys on Wallstreet this question, "Do you think Brexit will have any impact on Bitcoin?", they said "God no". From the illusion of Chinese buying up Bitcoin, to the jobs reports increasing Bitcoin, and now the stories of Brexit. It is market manipulation, plain and simple.
As an investor, I've lost confidence in the market because I know there is only one end to this, disaster. It never, ever works out. The last recession is a great example of this.
