For me crypto currency was always a mystery, but also very interesting. I recently opened my store and wanted to add something new, so I found this plugin. The set up is very easy and straightforward.

Awesome plugin if you are looking for crypto payment gateway for your woocommerce shop. Took 5 minutes to set it up and customer support was very helpful in answering all of my questions 🙂

Not good compared to bitpay plugin. 1. The orders are stuck in “on hold” status. They don’t send confirmation for sure. It is broken. 2. Spectrocoin gateway page does not allow to copy paste bitcoin address and value for people who want to pay from their wallet application on a website or software.

Features Needed ———————————– 1) No option to show company logo on the payment page. 2) Real name in your account is shown on payment page even if you are a business. 3) Default conversion currency is EUR. 4) No option to select the timeout period. It defaults to 24 hours which can lead to inventory being in limbo awaiting payment before it fails. 5) No overpayment or underpayment handling. 6) No ability to hide the language translations, select alternate ones, or choose a default language. Bugs/Issues ———————————– Gateway can take 10 seconds before showing the payment options. Not sure if this is a plugin, or server issue. Probably a server issue.
