I'm getting confused here because I don't understand what you mean by "you and your family depend on bitcoin to a large extent". Is there anything that bitcoin is doing for people and I'm not aware of it? Is it not alternative currency devoid of government control again?
Bitcoin as an emergency savings? I think you are having a wrong perception about bitcoin if you hold bitcoin for emergency case instead of holding for the future. Have you imagined having emergency when the entire market is bleeding blood or when the blockchain is congested and you need a higher fee to escalate your transaction? You really want to use bitcoin to solve emergency situation during such period? You'll definitely regret using bitcoin for your emergency.
If he really uses bitcoin as an emergency savings, I wonder how he will survive and get through the economic crisis of 2022. If I remember correctly, during the 2022 bear season, which was also a period of economic crisis, the value of bitcoin fell more than 75% from its all-time high in 2021. If his savings were in bitcoin, it might not lose 75% but it would lose a significant amount of value. I am amazed at how he solved the problem and was able to survive until now.
No offense but I guess he doesn't know what he's talking about.
Meanwhile people who save are smart but money saved will just decrease in value but bitcoin rises so if you want to save money for emergency purposes it is better to put it into bitcoin to make sure that it fights against inflation.
