See here is the problem wrapped up all in the posts.
Instead of looking at it as an investment it should be seen as a decentralized currency, where a canadian prime minister cant seize the funds of people who disagree with his politics or an american president and congress spending more money than their mint can actually print.
Bitcoin didnt grow in value initially due to people investing in the product hoping to see its value grow by other speculators.
Bitcoin was the "unofficial" currency of silk roads, the value grew due to the demand for the currency outgrew the available units.
sidenote: If I remember correctly at the time of the the arrest of Ross Ulbricht, the fbi siezed 145000 bitcoins. I wonder if somewhere in an evidence locker sits a hard drive with todays value of (145000*30000) 4.35 billion dollars. Are the passwords of the wallets written down in some court document?
I also believe Ulbricht should be set free; as he was railroaded by the US FBI and IRS as to make an example of him. No evidence that he was involved in any actual dealings was ever presented and all his crimes were conspiracy based.
