I've been watching the BTC price for a little while now and I'm wondering what peoples views are on the reasons for the fall in BTC price.

People selling BTC cause they are worried about auditing while they bought thinking it would be a good store of black money.

Old coin being spent in shops and businesses. These companies auto sell, so effectively people spending BTC they've stored for a while pushes BTC down.

Drops perpetuated by fear as people look to get out while BTC goes down hoping to hitch a ride when/if it rises again.

Rises in other markets that are attracting investors away from BTC (exacerbated by the fall in BTC price).

Market manipulation with strategic aims.

Looking at the previous months it seems the fall in price seems to go against the news of increasing adoption, so I'm wondering what's behind the fall and what the likelihood of a rebound is.
