Hi all!
A couple of years ago I was really unhappy with Bitpay, so I coded a universal solution to accept Bitcoin on any website:
https://github.com/Overtorment/Cashier-BTCIt is opensource and being used in several companies around the world now (no big names here, afaik). Recently I got tired of high fees and low Segwit adoption and rewrote it completely to support Segwit (P2SH addresses for now, bech32-ready; will be pushed to production, Im waiting for the spec to be formally approved and stripped of 'draft' status). Also, it relies on the one and only Bitcoin Core, so it is completely independent from 3rd parties (and using it helps strengthen the network!)
It does require basic web-development and linux skills to install and use this, but overall it is simple.
If you're unhappy with Bitpay (or any other bitcoin processor), want to enjoy Segwit and low fees, don't want to pay any cut to middlemen - I encourage you to try Cashier-BTC. It's opensource and free.
I also provide free support if you are having any issues, just let me know, would be happy to help. Spreading the word would also help increase merchant adoption!
https://github.com/Overtorment/Cashier-BTC so it's perfect for me by any chance would you have a tutorial video? or an online user tutorial? thank you in advance
