People earn money from this! Learn how they do it!

Hello friends! I have recently found out one interesting way, on how people earn money. I wanted to share it with you, so you can judge, is it opportunity or a waste of time. 

There are many websites and mobile apps, that pay people for taking different surveys and offers. We all probably hate that kind of stuff, but here is what I learnt. Many of that kind of websites and apps are paying for watching videos.

You can make an account and use it for specified number of devices. People make accounts on many different sites and use a few devices for every of them.

The key thing is to use as much devices you can and to use as much apps/websites you can. There are three options. For laptops and desktop computers, you can use website version and for mobile phones (tablets too), there are android and/or iOS apps. 

The thing is to play a video on your device and let it, plugged in, to show videos for a whole day. After a day, you earn money. On some sites, you earn 0.1 $ and on others a 10$ a day. It really depends. 

One guy have calculated electricity costs ( he have over 70 active devices) and he says that they are very low. So, electricity should not be a problem. The real problem is to gather enough devices. 

There are many options, from buying old or damaged (but still working) devices from a fiends to buying cheap online (amazon.com or eBay.com). I researched and can say that, good enough devices will cost you from 40 to 50 dollars. 

People who have already tried this method are earning over 1000$ with about 50 devices. So, if we can gather 10 devices from home and family, than buy 20 for 50 dollar each, we could earn 600 $ a month with one time purchase of 1000$. I do want to try this method, but with smaller amount (10 - 15 devices), just to see if it works for me. 

Here is a website of one guy, who is doing this: https://thetechslugs.com

When I try this, I will share my experience with you. Please guys, comment your thoughts, is it worth trying?
