First thing, keep it a secret. If invested in 3% bonds that's $30,000 for every $1m.
And 2.5%ish of that would be lost to inflation...
And then you'd lose a large portion of your principle when a ton of these municiplaites and state issued bonds that make up a large portion of bond funds go into default, and they are forced to file bankruptcy in the near future due to loss of tax revenue due to Covid shutdowns, non-renewals on leased property, falling commercial property values, underfunded pensions and other unfunded liabilities and the overall general fiscal irresponsibility of their mostly democrat leaders over the last 20-40 years. Pelosi has been pushing for $2 trillion to bail out these Dem run cities and states and that's what Trump and the senate have refused to do. It's coming, wait and watch.
