There was a thread a while back about Bitcoin, but I'm interested in what experiences people have had recently, if any.
If you haven't heard of Bitcoin, try: http://bitcoin.org/en/
I am in the process of installing a client, and so far have not actually used it (it takes a day to synchronize with the network), but I wonder if anyone has any positive or negative comments about it? I notice one frequent poster here asks for Bitcoin "tips" by putting his Bitcoin address in his signature. I wonder if that leads to any significant income?
From what I can make out Bitcoin is a peer-to-peer payment system where there is no central authority. A useful aspect, compared to paying by credit card, is that you can make a one-off payment to a particular person of a particular amount. Contrast to giving out your credit card number where you hope they will take, only once, the amount you have agreed to pay. If the person with your credit card number takes out more, uses it multiple times, or carelessly loses it, the best you can hope for is to reverse those extra transactions.
I gather that Bitcoins are worth what people think they are worth (well, you could say that about anything) and are currently trading for around $US 1000 per Bitcoin. You can make payments in fractions of a Bitcoin so that is not a particular problem.
