If your government introduced a new currency, it will allow ALL citizens to buy into that currency (money) at the same price. Each person would convert their existing cash into the new currency at the same exchange rate.

This isn't what is going on with crypto - early buyers...

paid very little to buy in and now, the latecomers are being asked to pay 1000s of % more for the same crypto "currency"!

In other words, the sellers of crypto are robbing the new buyers of their purchasing power by offloading the same crypto "currency" at much higher levels.

Think about this rationally -

Throughout history, did a group of people ever make billions of dollars from buying into a new "currency" early and then promoting the said "currency" to the masses?
