They would never get away with this as a publicly traded company.
Tesla, a publicly traded company, got away with buying $1.5 billion in Bitcoin just fine.
PayPal can also sell that Bitcoin to customers who want to buy Bitcoin.
I'm replying to a comment saying they should use their cash reserve to buy bitcoin instead of dividends/buybacks.
And yes, they can sell it and have some level of "float" to support crypto buy/sell exchange. But the comment was a hodl comment to "make them more money."
Unproductive investments are basically the constant increase in stock and housing prices over the last decade. You're not buying those to make more money, there simply is no other place for the money to go. The only way the savings rate can be reduced domestically is through unemployment or underemployment. Unemployed people don't earn money but they still have to spend, which reduces savings.
It's a truly hopeless situation for the humans living the USA. But hey, at least the dollar is still "good".
Oh right, presidents are taking on debt to cancel the savings glut that was forced upon them. That's a bad thing.
