3600/coins a day mined at current prices = $1.1 mil. which equates to $33/mil/month. That much money needs to flow into BTC JUST TO BREAK EVEN. Miners and electricity are fawking expensive and they dump the coins to pay the bills.
The reward half will help but that's in 80 weeks! And even then 1600 coins will still be coming out for 4 years. So at current prices that would mean Still another $15/mil a month. This is to just cover the new coins. If anybody spends other coins then more money needs to come in to cover those.
It's really not that hard to see why BTC will be on a downtrend for a long time.

Seriously, the blockchain is a public ledger. Just look it up, instead of speculating.
