I want cryptocoin to work but…
Look at what happens when a market like Silk Road for example (
http://money.cnn.com/2015/10/06/technology/bitcoin-silk-road/) get seized. The government auctions off the coins. Whether or not that was all the bitcoin available after the seizure is up to you. I'd imagine they kept some for themselves for reasons which will be upcoming.
The Mt. Gox hack was also probably state-supported, and I'd imagine whichever government pulled it off is either keeping them or selling them in small bits to avoid suspicion. The blockchain might audit everything but it can't tell people what is actually going on behind the scenes.
If a large bank like JPMorgan (
https://news.bitcoin.com/after-the-boss-calls-bitcoin-a-fraud-jp-morgan-buys-the-dip/) is getting involved you can be sure that the game is rigged, somehow.
If a real state actor wants to shut everything down, they'd be working it perfectly at this point - get everyone to put their money in to a specific coin type and then completely shut it down by crashing the market. If you think the NSA isn't the largest owner of bitcoins, well, I'd probably put my tinfoil hat on.
Since the hat's on anyway, China's shutdown of their exchanges (
https://arstechnica.com/tech-policy/2017/09/china-may-be-getting-ready-to-ban-bitcoin/) is another example of how the US government may be in control of the whole scheme. China's seen the future of the crash and is taking preemptive measures.
But all that being said, I already cashed mine out, so I might be biased.
