I read this many many times,
Is there any solid fundamentals in the conception that 1BTC could be worth USD 1 MILLION or even more?
Fundamentals are that value of USD is reducing daily. over last 50 years and will only increase in the future. Last year M", so money supply of USD increased 26%. That has to reflect to the value of dollar.
