BTC only has 2 Uses,
1. Store of Value
2. Transmission of Value
That is it , nothing else.
Gold has real world uses in multiple fields that nothing else can be used for.
And when the price of gold drops these other uses , create a cushioning to it's price drop.
BTC is losing it's 2nd uses, due to the ever increasing fees.
A Virtual Store of Value that is not easily transferred is beyond stupid and has little value,
because at the end of the day , a massive expenditure of Fiat is required to keep the Energy Wasteful BTC running.
As block rewards drop , and transactions are so high , that everyone uses cheaper & faster alternatives.
Guess what , BTC then loses it #1 Store of Value usage and the price crashes to ZERO!
And it has no other uses to stabilize its price on the way down.
People need to study this term Priced Out of the Market . (This is what is happening to BTC right now)
