I worked for a N.A. bank and on good day I'd take in anywhere from $35-$50M in US Treasury bonds. All payable to the BEARER. Don't think I wasn't tempted. lol. I had one customer come in one day with Whoops coupons. I had to tell him to take them home and frame them. https://www.investopedia.com/terms/w/whoops.asp I did end up buying some 10 year treasuries during the Jimmy Carter days. Would I love to see a yield like that again.
