Ugh so much I have to address from that.
First, why would untraceable payments be a problem? Seems like a good thing. What you should be worried about is reversibility and for that Bitcoin is better than cash (or any other existing payment method). Bitcoin payments are completely irreversible so they are safer for the provider versus cash. If someone hands you $500 cash, they can take it right back too if they overpower you. It has happened. Once a Bitcoin payment goes through and is confirmed (about 15 minutes), it cannot ever be reversed. Anonymous does not mean it lacks protection. Silk Road operated for years out in the open selling illegal drugs and mercenary type weaponry including tanks! - it took the CIA, NSA and various international spy agencies literally years to shut it down because the Bitcoin payment system is virtually untraceable (they eventually shut it down by tracing IP addresses and monitoring specific computers they knew were being used by offenders). Hundreds of millions of dollars was traded on silk road over the years. There is a good reason for that.
Bitcoin dead? Hardly. The news media doesn't get it yet either so I understand. I keep over $50K U.S. in BTC for a rainy day, and I haven't pulled any of that out despite the recent attacks (which I expect will continue.. and probably get worse once governments like China start to try to take Bitcoin down because they will eventually realize it poses a threat to their authority). Bitcoin prices have been very stable on most major exchanges (look at Coinbase, btc-e, bitstamp). I can buy and sell Bitcoin all day long on the exchanges (or even better, to locals via a meeting at Starbucks). I did over $2,000 today alone, selling above $690 per BTC. And I can still buy just about anything I want using Bitcoin on Overstock, TigerDirect, and eGifter (among several hundred other smaller vendors).
Bitcoin is hardly "shutdown" - despite the attacks in recent weeks, the price of a Bitcoin is still about $690 close to where it was before Mt Gox shut its doors (but down from the $1,000 high it hit last year). Mt Gox failed after being attacked by hackers, but Mt Gox was no more than a trading platform and a relatively small one by the time it died. I have never even heard of Flexcoin but it sounds like a very small bitcoin bank that got hacked and failed. How many U.S. banks have failed? Does that mean the dollar is dead (of course not, yet)? These failures have had almost zero effect on the other exchanges like Coinbase, Btc-e, and bitstamp. The BTC price went down for a few days after the Mt Gox news mostly because people didn't know if Mt Gox was alone (it was). Then it went right back up.
Accepting Bitcoin doesn't mean you have to take any risk though, unless you choose to do so. Using coinbase (for example; there are others) you can accept BTC and convert to cash immediately, so there is no risk of the BTC disappearing (of course, the same can't be said for the U.S. dollar, which could very easily devalue once inflation starts in which it must). In that respect it is a little like Paypal. Of course, like Paypal, Coinbase will create a record of your deposits (so you need to report to IRS) **but** no record of who sent the $$ or why.
Could someone break into Coinbase and steal coins? I suppose, but their security is as good as a real bank. It is pretty unlikely. They were immune to the attacks that hurt Mt Gox.
But, if you can get comfortable with BTC price stability (or actually, with the fact that BTC is likely to rise rather than fall over time), the best solution is to keep your own wallet, and encrypt it (or even better, print out your wallet keys and store them in a safe). This is virtually unbreakable security if you encrypt.
If you get comfortable with the "risk" of BTC itself (e.g., you realize that BTC hasn't failed yet, has been incredibly stable or increasing in price over the past few years, and its not going to go away anytime in the near future) then you can be completely anonymous and 100% immune from any theft by keeping BTC in your own encrypted wallet, offline and out of reach of anyone. Then, you can spend BTC just like dollars except anonymously at Overstock.com, TigerDirect.com, eGifter.com (which lets you buy egift cards at hundreds of retail stores like Home Depot, Lowes, Sports Authority, etc.). You can easily live off of BTC. You can sell BTC to others at a decent markup. You can hold BTC as it increases in value. You can transfer it to Coinbase (or your preferred trading site) and sett for dollars (or Euros, or whatever).
Bitcoin was made (literally) for businesses that need to fly under the radar of LE. I just don't get the fact that it hasn't been embraced by this particular community yet.
