So in summary, Bitcoin should not be adopted, because it is not adopted.
I'm saying it currently is not a money, and there is no reason to expect that in it's current design/implementation that it will become a money.
You can give just about anything to just about anyone else.
No.
?
Bitcoin has utility for me, since I transfer money across the globe all the time and many of my acquaintances already use BTC.
So bitcoin has utility for you because you can send them to someone else, and it has utility for them because they can send them to someone else, etc., etc..
Sounds pretty circular to me. It leaves out the original reason for anyone choosing to acquire a bitcoin in the first place.
Let's discuss what bitcoin is at a slightly lower level and then ponder why anyone would want to use it:
Bitcoin is a decentralized ledger of which people can decrease a number associated with one of their private keys by some amount and increase the number(s) associated with one or more other private keys by a total of no more than the same amount.This makes it's uselessness for most people even more obvious. Who cares about those numbers in the first place? What meaning do these numbers have to people? Since these numbers are not representing something people already value (hopefully you're wondering why someone would bother to create a ledger for something they didn't value?), they only matter initially if you falsely believe (or more strangely, pretend) they represent money (this would be the sole source of their valuation).
After a quick read of
http://wiki.mises.org/wiki/Money (and perhaps a more detailed read of some of it's sources), you can understand bitcoins are of course not money. The system as a whole is obviously not money (people aren't trading the blockchain or the software/rules that make bitcoin what it is). Bitcoins are not even a commodity, let alone a money. Bitcoins don't even have a single use. You don't use bitcoins to use the ledger, you use private keys to manipulate meaningless numbers (bitcoin "balances") on the ledger. So if bitcoins don't even have a use, and you're not even trading bitcoins but are rather just manipulating the ledger, but the ledger and the system that sustains it is non-tradable, what exactly is the money part of bitcoin? How does changing some meaningless number in a ledger even provide any value to anyone (outside of extracting goods/services from other people that believe a bigger number associated with one of their private keys on the ledger means something)?
In bitcoin's current implementation, it is
at best "metaphorical money"...I personally don't recall ever hearing of a "metaphorical money" and initial results from a google search don't turn up any relevant pages about
metaphorical money, which suggests to me it's probably not something that many people value...
As I said before, as long as enough people falsely believe bitcoin is money or that it has the potential of becoming a money, it will likely be traded, but only for as long as enough people continue to believe this. That's why bitcoin was ever traded at a price to begin with and why it still has a price. But unless some changes (to be shared at a later date if not discovered by someone else sooner) are made to the system, bitcoin's price will eventually drop to whatever price the few people (those that will just not stop believing that it's a money or has that potential) will pay for it.
If people do learn of the changes necessary to give bitcoin an actual chance at becoming a money, and those changes are not implemented in bitcoin, someone else will implement them in a competing system, which, unlike bitcoin, might actually have a chance at succeeding in the market. This means people leaving bitcoin for the new system, and would-be bitcoin adopters adopting the new system instead...not good for future bitcoin prices.
So why would anyone care to "buy bitcoins" (the metaphor for person A giving person B a good in exchange for person B to increase a number associated with person A's private key) in the first place if it's not due to a false belief that bitcoin is, or will become, money (again, other than to extract goods/services from others that falsely believe it is or can become a money)?
Prices dropped hugely, and we haven't seen a problem.
Difficulty never caught up with the ~$30 prices (it was only in that range for a few days, and only above $15 long enough for a couple difficulty changes, and declining ever since), so mining is still slightly profitable for most miners in the $4-$5 range at the current difficulty (which is not much lower than the highest difficulty). However, the price does not need to drop much more from current prices before most miners would be running at a loss. Prices suddenly dropping to the $2s would probably cause a huge percentage of miners to stop mining...down to $1 would probably make it unprofitable for well over 90% of miners at the current difficulty. Without a special (blockchain forking) software update to create a special case to adjust difficulty downward faster in that situation, it would take many months if not years (depending on how many stop mining) for the difficulty to adjust enough to get the block generation rate back to ~10 minutes. Unless they want to mine as a charity for the network they're going to stop mining. If they still want more bitcoins, most would be financially better off to just buy them from others rather than mine them at that point.
Namecoin solved its issue with merged mining (hopefully in effect in a few hours).
Yes, many bitcoin miners will likely help prop up or further increase namecoin difficulty (not necessarily namecoin prices) with merged mining, but if bitcoin prices drop far enough that bitcoin mining becomes unprofitable for most miners, both bitcoin and namecoin will end up in the same situation that merged mining is supposed to get namecoin out of. Unfortunately for bitcoin, there is no larger, more popular blockchain network to piggy back onto when bitcoin becomes unprofitable to mine.
