The following overview shows the biggest currencies of the world, according to their market cap:
What do you think? How high will BTC go in the current bull market?
My best guess would be: between Gold and the HongKong Dollar.
If BTC goes to 100'000 $ (which I think it will), it will be about the size of the HongKong Dollar.
To reach the size of Gold, BTC needs to go to about 400'000 $ (I don't think that will happen).
So until the end of 2022, I expect BTC to become the 6th, 7th or 8th biggest currency in the world.
Have a nice week!
