3) Contrary to popular belief, spending Bitcoins does not make them more valuable or bolster their market price. In fact, the opposite is true, when you sell a Bitcoin in exchange for a good, you are expressing a preference of the latter over the former and increasing the supply of Bitcoin while decreasing the supply of goods. In other words, every time you sell a Bitcoin, whether for USD or a good or service, you are increasing the market supply of the coin and thus it's relative price will be slightly less. Consider the counter-factual: if nobody ever sold a Bitcoin for anything, it's price would rise to infinity. If your goal is to increase the BTC price, don't ever offer them in a transaction for anything.
Sorry have to call B.S on that. Ok I appreciate its a complicated system but lets consider:
I have these special 5 rocks, they are pretty and there are no others like them in the world. I have all 5 so they must be worth unlimited fiat currency right? WRONG
See you have no interest in my rocks, they are not useful to you hence worth nothing to you.
The only way bitcoin is worth anything is if its useful to people thus making them want it... on the simplest level being if they can be exchanged for goods.... the only reason merchants will work to accept BTC is if people spend BTC, then we have all sorts of cool stuff you can get with BTC, then maybe people will want to earn BTC, thus BTC for services and labour....
Hoarding BTC does sweet F.A for bitcoin.... in fact I'd only hoard if I was confident in everyone else doing the right thing and making it worth something regardless of my not being involved.... thats one of my other gripes about early adopters being a security threat to the btc money base but thats another thread :-)
If satoshi is dead he'll be frikin spinning in his grave at your comment.... BTC is only worth what someone will trade for it.... the fact it interfaces with other currencies is only as a vehicle for others to acquire the currency, supposedly because they want to spend it.... or worse still they want to join the hoarders.
Thats my 2c
