TLDR: Whats it say? I heard its quite neutral. Correct?
It is surprisingly neutral, yes, and it's fairly accurate as well. One of the best neutral reports on Bitcoin ever, definitely.

A very well written and constructed article. They actually acknowledge the innovation of Bitcoin; some detractors say that Bitcoin offers nothing new, but it isn't always about the ingredients but about the recipe that makes something new. The ECB definitely recognise this. They have researched the topic well and provide numerous references for their statements.
While it is mostly uncontentious, there are a few points that would be worth addressing: the various risks assigned to Bitcoin. It is hard to accurately discern what proportion of these risks are a result from the lack of popularity with Bitcoin. They mention liquidity and operational risks but minor/ exotic ''real'' currencies can also carry similar risks. They don't quite seem to draw that parallel.
