Never heard of this Crypto payment gateway I usually test some payment gateway on Wordpress since 2020 but this (blockbee) never heard of them.
So how are you sure when you publish your service? 2018? I agree with Dave how can we trust a service or software if you lie.

Another thing is that the open-source code from this link below it does not have much activity but it has a record for last year's activity which is not enough to tell that this business is legit.
