ebay / paypal ........ I just don't see it in a million years
1) Its direct competition to bitcoin
2) ebay / paypal love reversing transactions. How can they reconcile that with bitcoin?
It will be reconciled because sellers can offer a cheaper price without the threat of reversals, (and likley less fees) and thus attract more buyers and traders, and so that market of sellers will displace trade from ebay, causing eBay to die or adapt
