It's pretty obvious looking this chart that next key support levels are the FairPriceLine (5500$ this month, look my bitcoin price model v1.1) and its 95% lower confidence level (4200$ this month).
18 months kama average 1st lower price deviation level is at 4200$, providing support; as i said I expect the next bottom to fall inside the 4200-5500 usd price range.
About Europe, the new AML V directive (jan 2020) is not good news, the authorities have decided to crack down on the bitcoin trying to kill its ecosystem with colossal legal burdens for all those who want to enter this business, sad news.
The next step will probably be to make illegal any anonymous detention of bitcoin even for private individuals, IMO anything outside the banking system will not be tolerated, the original vision of Satoshi Nakamoto is at risk.
