People always look for some recent positive events when they try to explain why Bitcoin has recently increased in price, but it just doesn't work like that - the fact that in other cases similar events don't affect the price shows that the correlation is very weak or non-existent and this is just a coincidence. The real reason why Bitcoin is growing in price is because it's technology is working, it's stable and reliable, yet at the same time it continues to improve.
I agree that people like to look for news events and correlate them with price changes and it is not true in part of the cases.
but on the other hand i do not agree with you about the tech part.
The jump was anticipated by some good part of TA.
I believe that mostly that price fluctuations are more psychological phenomenon than anything else.
