Which of these 3 companies are halal?

Assalam alaykoum Shaykh.

may Allah firstly reward you for all that you do and protect your family, and I wish you a blessed Ramadan.

I had a question about investing in bitcoins in the three following companies. I have tried to do an analysis myself via the PDF u gave, but cannot really judge whether these companies are halal or not. It concerns the following three:

  1. Polygon
  2. 1INCH
  3. INJ

Someone else told me that buying alt-coins is not an investment in the company itself, what you buy has nothing to do with the company, i.e. your money is not used to build the platform or grow the business. To what extent is this correct?

I would really love to hear about this also.
