You are confusing pre-mining with mining. You are confusing people willing to sell with people willing to buy. Your understanding of Bitcoin is upside down. It needs just to take a look to Argentina and Venezuela, to say the least, and understand the usefulness of Bitcoin. But let’s assume this is all a Ponzi Scheme, nobody is forcing people to buy and nobody is forcing people to sell. We’re wondering why you are spending your precious time to indulge in a supposed “Ponzi Scheme” while not complaining for the same issue on the website of your national Social Security.
We suggest you to attend courses of Bcademy, if you live in Italy, so that you’ll be able to catch the real meaning of Bitcoin and crypto in general.
