I think the price reduction of bitcoin is a normal phenomenon, it is a very normal adjustment.
A lot of people saw a lot of falls, and they said they broke, I don't think so, I think of it as a correction, so it's better to go up.
A 30% drop doesn't seem like a normal adjustment to me, seems like either market manipulation or a panic sell.
It is a living market - there are so many factors which contribute to the up and downswings of a token with as much liquidity as bitcoin.
From:
a) Market manipulation
b) Longs/Shorts being called
c) Bot Triggers
d) Greed
e) Fear
f) Safe havens
g) Speculation / store of value
h) Utility
etc etc
The utility of bitcoin has been decreasing as transaction fees increase, and yet BTC price rose massively in spite of this. I understand it is difficult to understand the exact cause behind the price movements, but still I think we can narrow down the changing parameters if not understand the whole driving force.
