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.
i think they already know that, this is the problem, they simply find bitcoin not be worth as a better alternative, because of its downside about security etc...
something must force them to switch at this point, like hoping for infaltion to increase even more, around double of what it is now(14%+), thus making them lose heavily money, maybe by then they would switch
