Is it still safe to keep bond ETFs despite the low interest rate or should I cut them loose and reinvest in Dogecoin?

Your initial strategy of investing 10% of your cash in the ZFL bond ETF was good thinking.

The monthly dividend of $0.043 is definitely appealing enough. This is more than you would get with your savings account with pretty much the same level of risk, so be sure to hold onto this bond. The volatility is also low, which adds another point in its favor.

Over the next year, central banks will begin to raise interest rates to tackle growing inflation, so you are going to have higher yields in the future. The Bank of Canada's guidance from its June policy meeting suggested that it will likely begin to raise rates in the second half of 2022.

If this ETF represents a small percentage of your portfolio, keep it!
