They're too late. The jokes on them. Bitcoin is no longer a payment system. You can't buy stuff with it anymore because now it's a "store of value".
You don't
really need a 10-minute confirmation do you? Give it a half day and you can drop the fees 7 or 8-fold. If people can load their accounts with BTC, I don't see on-chain payments as a big problem right now.
It can also be tempting to spend some of those bitcoin profits. Isn't that how the hodlers roll--never sell, hold until you can spend it? Not sure how much business eBay does, but if Amazon were to enter the foray, I think it would generate a lot of profit taking.
By the time they implement it as a payment system, the Lightning Network might be in place and the scaling will be ready to handle that kind of load. Bitcoin in it's current state, will not be able to handle transaction volumes that eBay would bring to the network. Not even BCrash will be able to handle that kind of load. {..but Roger Ver will tell people that it will be possible}
Saying that the problem of transaction volume will soon be solved by the Lightning Network is like saying the traffic problem will soon be solved by flying cars.
A specification for LN has now been released, and they've done mainnet transactions. How far off do you think we are? A year, two? Realistically, the next big step is building publicly available wallets.
