Re: I don't like the idea of governments holding millions of Bitcoins.
The only possible impact is on the market with selling pressure that can trigger market panic sell, and price can be dumped in short term while in long term, people can realize that market dump from someone's sales even a big Bitcoin whale, is good opportunity to buy cheap bitcoins.
This is approximately what I was talking about. The concrete scenario is in a situation where there's a controversial feature and some big entity like a government threatens to sell the coins on the chain implementing the feature to pressure the developers. Just read the first page of the thread 
To many concerns regarding on their future actions but I guess people should careless about what's currently happening since what's important is they buy and add for demands on Bitcoin.
Depends on what your personal goals with Bitcoin are. If you want to get some bucks more and then sell to a greater fool, then I agree. But in all other scenarios, fighting for BTC staying censorship resistant is the best strategy and will also probably lead to the highest possible market price in the long term. A BTC losing censorship resistance may eventually crash as it would become a slow, inefficient and risky PayPal, to say it bluntly.If it happens that they are the one who will dump it in future then I guess what we need to do is to be prepared on their future actions. But for now it seems that they don't have plan to sell nor even control Bitcoin on full extent since so far they provably know that they cannot do that.
Currently the coins in governments' hands are too few, and there are also not many governments really stacking. But my concerns are for a future with a race between governments to be first. Not all will have the same goals, some may dump the coins later (and that would be ok), but some would probably like to buy influence on Bitcoin's development. See the OP.And administration changes with policy shifts are completely normal and should be always expected. It would even be healthier if there was some fluctuation in that regard.
@hero_the_bossman: Agree.
