For e-commerce I doubt that since Bitcoin is doesn’t have replay feature which is vital for customer refund policy especially of e-commerce. It was implemented before on our local e-commerce but they remove it later on due to the refund issue is frequent on this business sector. Imagine paying 1$ to 2$ of fee just to refund the customer funds which is a huge loss for e-commerce if this will happened to multiple users in daily basis which unlike cash that doesn’t charge/charge minimal on transaction transfer.

I think e-commerce will just stick to fiat which is working already rather than make it complicated just to cover the minority that use fiat too with their purchase.
