Thanks for asking. https://passiveincomemd.com/what-is-passive-income/ gives a good summary of the definition I use. But in brief, it’s income that isn’t proportional to the time you physically put into acquiring it. It doesn’t mean it’s not without work or effort. It’s just that most of the work is done up front and it continues to pay off long after that initial effort. Real estate fits into that box. There’s definitely a spectrum but compared to what we do as doctors, where our compensation is directly linked to our time, most of these things are quite passive.
Real-estate crowdfunding ($9,600 a year): Once I sold my SF rental, it was natural to reinvest some of the proceeds into real-estate crowdfunding to keep sector exposure. I didn't invest a lot in some of my favorite real-estate investment trusts because I felt a rising interest-rate environment would be a stronger headwind for REITs. But if I could be more surgical with my real-estate investments by identifying specific investments in stronger employment-growth markets, I thought I could do better.
Very enlightening. I like that you have a number of discreet passive income streams working for you. I”m not sure about such a large CD/ bank holding though, though it looks as though its giving you a fairly healthy income. How do you feel about a rising inflation rate on your effective real cash return? I’m looking to diversify beyond my current dividend passive income. Rental income is what I expect we’ll be harvesting next. P2P lending is a little too out of my comfort zone. I had a lot of exposure to consumer credit risk models at a prior role, and it scared me the heck away from consumer lending!
'The influencers in order to communicate marketing messages to the audiences you seek to reach'. In business, it is indicated that people prefer interaction with humans to a logo. Therefore, it seems that influencers are on behalf of a company to build up a relationship between the brand and their customers. Companies would be left behind if they neglected the trend of influencers in viral marketing, as over 60% of global brands have used influencers in marketing in 2016. The influencer types come along with the level of customers' involvement in companies' marketing. First, unintentional influences, because of brand satisfaction and low involvement, their action is just to deliver a company's message to a potential user. Secondly, users will become salesmen or promoters for a particular company with incentives. For example, ICQ offered their users benefits to create the awareness of their friends. Finally, the mass reached influencers are those who have a huge range of followers on the social network. Recent trend in businesses activity is to offer incentives to individual users for re-posting the advertisement messages to their own profiles. A common type of an incentive puts all the re-posting users into a random draw for a valuable gift 
To fully understand the model, it’s useful to look at the second, and subsequent, cycles of growth. In the model above, only the new customers that were added in the prior cycle send out invitations. This is because it is highly unlikely that the entire population will continue to send out invitations every cycle. Every time I have looked at other blog articles or formula for Viral Growth, they appear to have gotten this part of the calculation wrong.
Domain names cannot be replicated. If one is taken, the only recourse would be to approach the owner to discuss a sale. While there are other variations you could choose, sometimes owning a certain domain (especially if it is attached to your business) can be worth the premium. Often, people will scout out domain names that are still available, buy them, and then sit on them in order to sell them down the road. Depending on who may want the domain down the road, you could sell it for a large markup.
