Bitcoin can lead the digital world as it is a powerful payment method.
It can not replace the fiat money ever, but it can be one of the top (digital) currencies in the world.
What is needed for bitcoin to become more popular is when big stores implement bitcoin and people will gradually pay attention to bitcoin.
You never know. With all this fiat money printing, maybe someday people will realise how the system is eating their savings. The other think is that the banking system is really rubbish.
This fiat money printing has been going on for years now. And all the corporates are cheering it.
Some day, this will come back to bite them.
