Price was going up with the announcement of Segwit and the possibility of a service like Mega attracting new users.
$750-800 seemed really easy to reach.
Then some news story about China possibly looking to regulate Bitcoin comes out and the price drops immediately...
(a news story with no source by the way)
I still think Bitcoin is a good long term investment, but the market is way more fragile right now than I was giving it credit for.
Assumption were wrong and speculation of reaching $800-1k have failed for this year. Bitcoins price is decreasing again as of now and it continues to drop again.
When bitcoin price increase rally rose up to $750+ , traders and some users do surely sell off their coins that really affects the price.
