It's true that Michael Saylor has a different mindset from most people I still think the original advice has its place not everyone has the same risk tolerance or financial backup as someone like him, for regular investors the idea of only investing what you can afford to lose is more about protecting yourself from emotional and financial stress but yeah his bold move does inspire more confidence in the long term vision of bitcoin.
Agreed.
Saylor can say many things, and do even more than some would imagine - whereas common retailers are not in the same position as him.
Still, he is projecting his views and optimism of BTC towards the broader masses - and that brings some results too.
