Hello
I don't know if I am writing in the right topic but I hope so.
I am trying to develop a support page where the members could mine a specific point. While the mining process, they would mine for example ethereum or other altcoin. All of the accepted status mining would be used to get the specific point.
For this, I need to show of course the mining options, how much cpu and gpu they want to use for mining. I would like to verify if the specific accepted value is valid from the website or it is invalid or from somewhere else came that accepted value. If it is valid accepted value and it came from the donation website then the person would get the specific point. I wouldn't like to verify on the javascript side because that could be manipulated therefore I would check if the accepted value is valid in the php.

Is there somewhere an open source for this? At least some parts for this which is not very old? I saw some which is 10 years old and the newest is 3 years old but hmm I don't think they would be good enough.
Thank you in advance the answers.

Hello
I hope that I am writing my question in the right topic first of all.
I am trying to use my bitcoin on one of the Mihoyo game but they want to have Visa or Mastercard. I am trying to find a website where I can use my bitcoin in Visa or Mastercard version without verify with documents.
I am fine to give mobile numbers and such things but not serious documents which can leak on the internet if the website is hacked. I don't trust any of the websites which want to have such documents because we don't know for real what they will doing with the information even if they mentioning that they will just use to verify the account if not fraud.

So is there a website which is trusted and not need to verify with sensitive documents to get a prepaid virtual card?

It is ok if that has limitations. I just need something temporary.
Thank you in advance all of the answers.

Edit:
I forgot to mention that I checked many websites on the Google but many of time wanted to have verification and some of them had bad reputation.
