Lending Club went public in 2014 and is now worth about $1.7B. They advertise P2P lending returns of over 7% for well-diversified portfolios of over 100 notes. I’ve personally been able to achieve a 7.4% annual return over the past two years in a completely passive way by investing in A and AA notes. Others have achieved a 10% annual return through relatively minimum effort.
However, you should pick a niche and blog about that. If you're launching a money related blog, maybe it'll be about how to make money in real estate or simply how to make money online. Pick the niche and stick to it. If it's a diet and fitness related blog, maybe the niche is the Ketogenic diet, the Atkins diet or some other form of diet or fitness.
A good portion of my stock allocation is in growth stocks and structured notes that pay no dividends. The dividend income that comes from stocks is primarily from S&P 500 index exchange-traded funds. Although this is a passive-income report, as I'm still relatively young I'm more interested in building a large financial nut through principal appreciation rather than through dividend investing. As an entrepreneur, I can't help but have a growth mindset.
