gold is not bitcoin, in fact they have nothing in common!
gold is getting its value from so many different usages it has. from obvious things such as being used as a jewelry to small things such as usage in electronics, and other parts of science as an element. and so on. so it doesn't matter if one idiot held 1 kilo of gold, the rest of the world were still using gold as it was meant to
bitcoin gets its value from being decentralized secure and also for
being a currency and for that to succeed people need to use it as a currency, if everyone just holds bitcoin in their cold storages that is the death of bitcoin in my opinion.
the turtle is gonna fall over and die!
