Exactly it looks like a downtrend... but in reality it is not !!!
Let me explain. Buying BitShares-PTS you don't own only BitShares-PTS but a percentage in future DACs (Decetralized Autononomus Companys)
Imagine someone has bought 1000 BitShares-PTS at 0.014 BTC (14 BTC investment) on Januar ( https://www.cryptsy.com/markets/view/119 )  and now he has "lost" 50% because the price right now is at 0.007 BTC....
HE DIDN'T LOOSE because he owns now about +650000 BTSX (BitSharesX coins that works with DPOS chain calculated with 2 billion suply) and NOT ONLY the first 1000 PTS...
That means (1000 PTS * 0.007 BTC) + (650000 BTSX * 0.0000170 BTC) = 7 BTC + 11,05 BTC = a total of 18,05 BTC that means a net profit 4.05 BTC (about 30%)
and we don't even have included the profits from a percentage in future DACs !!!  And don't forget that BTSX price is (in my opinion) undervalued because investors are still not very well informed and right now
the "product" is still in the testing phase (Dry Run  https://bitsharestalk.org/index.php?topic=5523.0
