Bond investing is making a massive comeback. You can reinvest into higher-yielding products as you receive your coupon payments.
I just received $17 of bond coupons and went shopping within my income investing portfolio.
By first filtering your money through bonds, you can protect your principal at all costs.
But, by reinvesting in high-yield products, you keep an income element in your portfolio-building multiple paychecks along the way. Good Luck!
