If you’re looking for some extra money these days, you’re not alone. More and more people are picking up side gigs to make ends meet, and finding extra income is particularly popular among Millenials and Gen Xers, with many reporting that they make, on average, over $10,000 extra a year thanks to a side hustle. If you’re looking for some ways to make some extra cash, here are a few unconventional methods to keep in mind.

Buy and Flip Liquidated Merchandise

If you’re willing to invest a little money and time into your side gig, buying liquidated merchandise can be a great way to make some extra money. By browsing liquidation auctions, you can see a broad variety of used, returned, and refurbished products from a wide range of retailers.

Whether you’re buying a pallet of Target customer returns or refurbished electronics from Amazon, if you can win the products at a lower price at auction, that leaves plenty of profit margins to make some extra money. Just make sure you have a place to store your merchandise and budget for shipping costs!

Invest in Cryptocurrencies

Buying and selling on a cryptocurrency exchange is a great way to make some extra money, provided you have the right information. While it isn’t likely that your cryptocurrency investment will make you an overnight millionaire, many people who can buy litecoin with credit cards have the potential to make a great return in as little as a few weeks.

Of course, it’s important to understand what you’re investing in before you put any money behind it, so make sure to read up on some crypto basics from a website like CryptoVantage before you use this strategy for making money.

Get Paid for Your Opinion

While not as lucrative as some of the other methods on this list, taking and completing surveys online is still a great way to make some extra money each week. Whether it’s completing a survey on your train ride to work or during your lunch break, getting a few extra dollars each week makes eating out or grabbing a drink with a friend a little less straining on your wallet. Here are twenty paid survey sites to get you started.

Become a “Mechanical Turk”

What’s a mechanical Turk? Put in its simplest terms, Amazon Mechanical Turks lets different businesses crowdsource various jobs and tasks to an online workforce who can work remotely.

Some of these tasks are research surveys from behavioral science departments at universities. Other jobs involve helping improve voice recognition platforms or image moderation. Different tasks pay different amounts, but once you get the hang of out, you can start making a pretty decent hourly wage.

Get Your Car Wrapped

If you own a car and drive often, you may qualify to get your vehicle wrapped to help advertise different products or companies. By just providing some simple information about your daily commute, general driving habits, and car style, ad agencies can pair you with a company look to wrap your car and pay you for it.

Depending on where you live and what you advertise, you could make anywhere between $200 and $1,000 extra a month. When you consider how much extra that could give you towards paying down student loan debt, the price of turning your car into a Red Bull advertisement gets much more appealing.

As you can see, there are all sorts of ways for you to make more money if you have the gumption and are truly interested in having a side gig. Whether it’s transforming your car into a moving advertisement, investing in the latest cryptocurrency, or flipping liquidated merchandise online, the sky’s the limit if you put your mind to making more money.
