NO FUSSING WITH CRYPTO WALLETS OR HARDWARE WALLETS If you buy and sell physical cryptocurrencies you need to make a decision on whether or not you leave your physical cryptocurrencies with your provider.
If you do, you risk they may be hacked. If you do not, you have to learn how to use hardware wallets where one wrong keystroke could mean all funds are lost.
Crytpocurrencies are not widely accepted as payment for goods and services. No need to hold them physically.
