It’s something akin to picking stocks. You want to buy undervalued domains, and sell them later on at a higher price. For example, you can pick a domain that is out of favor, but could be related to some future event. So if you decide that the stock market is likely to crash in the future, you can buy a domain that includes the words stock market crash during a rising market, and then sell it in a falling market.
If you are not comfortable in penning down your thoughts through blogs and content writing, make use of your camera to create a video presentation. Create your YouTube channel, upload videos and start monetising them. Choose a category or subject that you want to make videos on and get started, but make sure it's a topic that will interest a lot of people. Everything from cooking shows to political debates can find many takers on YouTube. You have to create a YouTube channel, which works on a similar model as a blog. As you make your channel popular and the number of subscribers grows, so will your earning potential. The payment one gets is based on every thousand views.
For those with a large Twitter following, you can make money from your Tweets alone with Sponsored Tweets. You could be paid for sharing a business’s information, recommending restaurants or hotels, or tweeting pictures of you using or wearing products. As with all sponsored posts on social media, businesses will only be prepared to pay you to Tweet if you have a large following that you can influence. So work hard on building up a loyal fan base.
The music industry might not be as strong as it was in the 80s, but there are still plenty of ways to make money online as a musician.

As long as there is still the written word, there will always be editors. Freelance editing and proofreading not only pays a decent hourly wage, it also gives you the chance to read about potentially interesting topics too. What's more, pursuing freelance writing & editing as a business idea can afford you a lifestyle that lets you travel the world as a digital nomad. You can find lots of job postings from companies and individuals in need of writing, proofreading, and editing services on Upwork, which makes this a high-demand opportunity to make money online.
– Project Payday is one of those sites that has testimonials of people who have earned thousands of dollars by getting paid to get trial offers. I’m not saying you’ll earn thousands, but it is legit and you can earn some extra cash. They assume that by paying you to do a free trial, you’ll either like the product and purchase it, or forget to cancel the trial and get charged for it. If you can keep track and cancel before you get charged (if you don’t want the product), then this is a great site for making some money.
CashCrate sends out literally thousands of payments a month to users just like you who spend time completing surveys and offers on CashCrate.com. How do they do it? Well, they do surveys and offers regularly. It really adds up! Your initial goal should be to meet minimum payout, which is $20.00. Making $20.00 in free cash is actually quite easy considering there are hundreds of surveys and offers available, but here are a few tips to get you to your goal faster:
A niche affiliate site often presents like an eCommerce store. To get started with an affiliate site, choose your niche then display products with pictures, descriptions, and prices, just as you would on an online store. However, when visitors click the ‘buy’ button, they will be taken directly to Amazon, to make the purchase. You then make an affiliate fee for sending the traffic to Amazon, but have none of the packaging hassle, or initial financial output creating or buying the products.
That “urgent” email from a wealthy Nigerian Prince who claims to have a fortune with our names on it, to the blaring online video by the latest rambling internet marketer who swears we can get rich by using their system, to the late-night infomercial that beckons us to try a simple system that countless others have used to get rich, we’ve just about seen it all, haven’t we?
Learn then selling guidelines. Each marketplace has guidelines that define what you can and cannot sell. State and federal laws also impact what items are prohibited. In general, you cannot sell alcohol, weapons, service contracts, animals or event tickets. Also, while not always prohibited, you may find restrictions on how you can sell items in some categories, such as art, gift cards and coupons. eBay, Craigslist and Amazon publish these guidelines on their websites.
Find a profitable niche. Starting with your interests, write down as many niche ideas as you can. Think about topics people might search online. Ideas include passions (like surfing or body building), fears (like spiders or speaking in front of crowds) and problems (like getting out of debt). Do keyword research to see it others are interested in the topic. Find out if a domain name is available that matches the keyword 100 percent. 
Drop shipping is another great ‘hands-off’ way to sell products. Firstly you will need to find businesses that sell products in your niche that offer a drop shipping service. Then you will need to create a website promoting and selling the products. When you make a sale, you take the payment on your site and then the manufacturer ships the goods to the buyer. The profit comes from charging a higher rate than the manufacturer, and if you are selling a high number of products this can quickly add up to a healthy revenue.
Set up a roadside stand. Depending on where you live, you could profit handsomely by setting up a roadside stand. If you live near a resort area, for example, you could buy cases of bottled water, put them on ice, and sell them to passers by for twice what you paid. Selling fruit and produce you grow yourself is also a smart idea in highly-traveled areas.
Before we go any further, let’s talk about the difference between active income and passive income. This distinction will be paramount to your ability to produce serious capital on the web. So what is passive income? Passive income, if you don’t already know, is income that’s earned automatically. It doesn’t require much maintenance once that income stream has been created. However, it does require an enormous amount of effort at the outset to establish that stream of income.
I also participate in online surveys through the following websites, that work in the US and internationally (I use them all and I'm based in Brazil, for example) - Opinion Bureau, Myiyo, and Green Panthera. All of them have a variety of surveys and pay well. All you need to make money is to have 20 min or so to answer a few questions every day/week and have an active Paypal account so you can cash out.
Daily Surveys can be taken one or more times per day. This is indicated in the survey description. Other targeted surveys can be taken as you see them. Be sure to complete these when you see them. Some surveys may accept a limited number of responses from people matching your demographics, and can sometimes disappear quickly. New surveys come out all the time too!
