I think also a very good way to earn a nice passive income is investing in Cryptocurrency, especially in Masternode Cryptocurrencies, which provide a passive income in coins, also those carefully picked coins grow in value, so it’s a double gain! And a great coin to invest in at the moment is GINCOIN, which is the fuel for a really succesful project. Find more at GINCOIN Website: https://gincoin.io/ 😉

The best way to take advantage of something like Airbnb is to have a separate property that sits vacant all the time. This way, you can just worry about keeping it clean and never have to worry about making sure you’re out of there when guests want to show up. While that’s not always the most cost-effective way (owning another property can be pricey), it’s the best.
To your point about Municipal Bonds, my concern is tax reform. While everything is mostly being worked behind closed doors (and likely wont ever see the light of day). There is still the chance they propose to limit the amount of the tax free nature of these bonds. While I dont sen panic in the streets, I do see a scenario where bond prices get additional pressure because municipalities have to increase rates due to people putting their money to work elsewhere.
But as with everything, there are cons to go with the pros. While a good viral marketing campaign can bring massive awareness about your brand in a cost-effective manner, it also has the capability to dilute your brand. Or at its very worst, build negative buzz regarding your brand and products. This is when “too much of a good thing” may just hurt your work in building your organization’s credibility.
In 2014, A.L.S. Ice Bucket Challenge was among the best viral marketing challenges examples in the social network. Millions of people on the social media started filming themselves, pouring a bucket of ice water over their heads and sharing the video with their friends. The challenge was created to give support for fighting amyotrophic lateral sclerosis (ALS), also called Lou Gehrig's disease. People finished the challenge and then nominated the next person they knew on the social media to take the same challenge. By following this trend, Ice Bucket Challenge became a 'fab' on social media with many online celebrities such as Tyler Oakley, Zoe Sugg and huge celebrities and entrepreneurs like Justin Bieber, Mark Zuckerberg and Bill Gates participating.[76] Until September 2014, over 2.4 million ice bucket-related videos had been posted on Facebook, and 28 million people had uploaded, commented on or liked ice bucket-related posts. And about 3.7 million videos had been uploaded on Instagram with the hashtags #ALSicebucketchallenge and #icebucketchallenge.[77] The ALS association didn't invent the ice bucket challenge, but they sure received a huge amount of donation from this activity. It raised a reported $220 million worldwide for A.L.S. organisations, and this amount is thirteen times as much donation as what it had in the whole preceding year in just eight weeks.[78]
I am an English major and a herbalist with so many ideas and no extra income to fulfill them. I recently started renting my extra apartment in the attic with Airbnb. It’s amazing how fast I accumulated some money for few hours of work between guests. Now I want to persue all my dreams of opening an online herbal store, publishing my ebook of treating Ulcerative Colitis with herbs, blogs, and videos, and pretty much all of the ideas mentioned here. I will save this article as its really helpful for whomever needs some ideas…
What's crazy is that my book income is more than my SF condo-rental income. Yet I didn't have to come up with $1.2 million of capital (the minimum cost to buy my condo today) to create my book. All I needed to create my book was energy, effort, and creativity. I truly believe that developing your own online product is one of the best ways to make money.

Your income is your greatest wealth-building tool—a tool that typically requires your active participation in the form of a full-time job. You know what I’m talking about! Even if you love your job, I’m willing to bet you wouldn’t mind earning some extra income without the blood, sweat, tears, and time commitment of another job. In fact, there are several benefits. Building a passive income:
In 2014, ad agency Ogilvy & Mather Paris set up wifi hotspots in areas of Paris that did not have wifi connections. But to use these special hotspots, you had to select the Scrabble network, create your best word, and earn free wifi minutes based on your score. Like regular Scrabble, players could earn more points with longer words. And if you shared your words on Facebook, you got to double your score (and thus your wifi minutes).
The reason to make use or virality, the ease in spreading and sharing, is however a double-edged sword. We cannot forget that in this type of campaign, a large part of the control falls into the hands of the users, and we risk the message being misinterpreted or parodied. On the other hand, a successful viral campaign can work miracles for your brand’s results.
