EBay considering accepting bitcoin as payment
Not that Btc needs Ebay...
From the article you cited: “PayPal’s CEO David Marcus recently tweeted: ‘We treat BTC and any FX the same way. We’re believers in BTC though.’”
That’s one similarity to a Ponzi scheme. Both take believers. Another similarity will be the end result when the believers realize they were wrong.
Again, for something to serve as a suitable currency, it must provide stability of value. Otherwise it will never gain general acceptance for that purpose. And bitcoin will never attain stability of value, ever.
It’s failure to maintain a stable value from one transaction to the next makes it impossible to budget. That’s what will keep it form ever becoming our next form of worldwide cash. Only those with extra speculative cash can afford to use it and since too many people live week to week it fails to meet their needs.
