Anonymity is limited only if you are acting really dumb (or you are extremely unlucky). IP address does not mean anything and can "hide" several thousand people. It only shows who pays the Internet bill.
Please do post something that speaks really against usage of BTC. It just sounds too good to be true, unfortunately I can't find anything negative about it.
Ever heard of people caught downloading copyrighted content from P2P networks? Many of them were caught by knowing who IP address belongs to.
Say you are using Verizon as an ISP. Under court order they may have to reveal that on such and such date range certain IP belonged to your account.
A negative against not the usage of BTCs (any currency can be used for anything) but against, say, stashing all your retirement savings into BTC is:
it is well known that more than 50% of the network is in old, dormant coins. Moreover, relatively few entities own the majority of all coins. The trade that is currently going on is just a comparatively pitiful number of BTCs going through a huge number of transactions. Only relatively few number of miners can and will be able to continue to mine, as not everybody can afford ASICs. With increasing difficulty the network is increasingly maintained by a smaller and smaller number of people who have the means that you can't afford.
So in principle, the BTC and the network were, are and will effectively be owned and controlled by comparatively few "rich people" or "reserves".
Note that I am not saying it is the same with fiat anyway. I have already heard the "argument" : if it is a scan I'll rather give it to Satoshi than Ben Bernanke.
I am just saying that concentration of "power" in a few entities is definitely not a positive, at least not in my book.
I read Torrentfreak.com daily, so yes I heard. I heard about infamous Davenport Lyons law firm who bullied a lot of random people.
The thing is - you either have brains & money to defend or not. The way I see it is we are in process of re-distribution of wealth - as always there will be fat cats and hungry dogs.
At this very moment there are people out there in the pub drinking beer and doing nothing - every day and every evening. I'm behind computer and seeking for opportunities.
Is it fair if everybody should be at the same level (financial wise) while some folks did nothing?
The ascii machine costs a few thousand dollars if it gives me power to control something (competitive advantage) I will buy it or will find someone to buy it for me and we will split the profit.
There is always a solution for any problem, so I would not say that any of what you said is relevant (at least not in my book), though I admit I might be terribly wrong.
