Like @logitechmouse said, volatility is one of the main factors on why people do or don't buy bitcoin, they are too afraid of losing all their earnings.
Also it might be the technology too, some people / most people in bitcoin don't even know how to sign a message with their bitcoin address.
Most "investors" use exchanges to hold their coins in and don't keep their private keys to themselves.
Even sending a transaction with a custom fee is a hard task for a beginner or some people in crypto because they are just profit-driven.
if they only knew that volatility is the main advantage of cryptos on why it is verry profitable . i think they will accept the risk if they really wanted to earn big income

its not that hard to sign a message because there are guides online that can be easily followed . signing a message is not really necesary before someone will use thier first bitcoin .
