It’s the best financial advice, covid is the marketing keyword to remind you, if you don’t spend every last penny in the wallet, you can never have a chance to spend that again. Spend until you drop you plebs!
I will not spend my bitcoins because I will hold them for the foreseeable future. I have given the password and private key of my bitcoin wallet to my wife and child, I do this because if I die, my wife and children can enjoy the benefits of bitcoin that I have. if we spend the bitcoins we have today then we will lose a huge profit in the future.
If you have bitcoins than fiat then that's an investment which means you spend your money to buy it, the advice is actually good for people hesitating in trying to invest their money into something. If you see it in another perspective it will help sure help mentally.
I don't really get, what does saving even yields for someone, we save every penny for a future which is uncertain and we can just die at any moment, and automatically our wealth is not ours anymore but our family's which is so sad. Eat good, travel and enjoy the life when there's still time, there's no good in saving for a future when one won't even have the energy or interest to roam the world!
If you only care about yourself then that's no problem and you don't have to force your ideology to others because we have different status and situation in our lives; I'll give you an example, if you spend every penny to invest its either you win more or you lose more, and some people are more comfortable in losing less and winning less than taking the risk of losing much than they could handle and unfortunately if you keep losing in this type of situation there is no return.
