Cryptocurrency is a great storage of value. Do not forget the value of physical assets if the shit hits the fan. Especially silver. Lets pretend for a second you need food. You may be able to trade bitcoin. If you need antibiotics you will also need bitcoin to buy it.
If you have pure silver it is a natural antibiotic. You may spend more Crypto to buy antibacterial medication, anti fungible medication, and it also kill viruses !
In other words silver is cheep and can save you the health of your families life but crypto's can't.
