Yes, I hold variety of Bond ETFs in my portfolio including High Yield Corporate and Government Bond ETF (HYG), Emerging Market Bond ETF (EMB), Investment Grade US Bond (AGG), Inflation adjusted US Treasury I-series Bond. I believe in keeping a diversified portfolio of different asset classes. All asset classes have different risk and return profile and have different correlations with each other. As for corporate bond being more risky/expensive than government bond, ask investors who invested in Greece Debt vs those who invested in Apple debt. You may want to consider reading up a few books in investing and finance. /r/personalfinance, /r/investing, /r/financialindependence, and /r/finance are a few good subreddits with some smart regulars. Also these subreddits have good list of recommended books.
