"Firstly , bitcoin is limited in number (21 million) and the world population is higher than that if not twice" higher than what? What the hell are you talking about? there about 8 billion people ionn earth. What hs this got to do with anything? Have you never heard of fractions before?

"if you invested in bitcoin at an early stage it would have made you twice richer" err ok? It will depends on when you bought them how can you say twice?

Right now I agree with you somewhat about the transactions. The high fees are not nice and not what crypto was really meant for.
