Where can I buy anonymous and without annoying smartphone App by credit card Bitcoins?

I would like to try crypto-mining with small starting amounts and have already got several wallets (hardware and online).

Also, I have already found two interesting mining providers and set up an account there, so that the receipt of earnings from the mining business is guaranteed.

However, you have to invest in both mining companies already in the respective cryptocurrency.

So now I'm looking for a platform where I can buy credit card or bank transfer crypto currencies and then invest on my wallet in the mining company.

This platform should meet the following requirements:

-All operations can be done on the desktop or notebook (I annoy the many bad apps easy and also smartphones are too unsafe me).

-The platform also accepts offshore companies or the settlement is done anonymously (Not that I'm misunderstood: I'm willing to reveal my identity to this platform, but the settlement must be done through my foreign company).

-The payment is made by company credit card, company account or possibly PayPal.

- Of course, a certain degree of security should be given.

Just write a few suggestions; - I'll pick the right one for you.

My transfers are done with bitpanda. Of course you have to verify that I do not know if you want that. https://web.bitpanda.com/user/register/343557009401803892
