There are many places online where you can get money but you have to pay out to get it. These include things like setting up a website, investing money, paying someone to find you work or things like this. These may not be wise things to do anyway, particularly without careful reserach and if you have no money, you will have no choice but to avoid them.
Luckily there are also places online where you do not have to pay money to earn it and so these would be the places to look at. Firstly if you items to sell then using a social media group could be wise. There are no charges for selling on them and so it is worth a go at listing some and seeing if you get any interest. You may only be able to sell locally, but it will be a worth a go as you never know who might want to buy things.
Alternatively you could see whether there is any freelance work that you could do. There are websites which bring employers and employees together and they will have lots of jobs that you can look through and see if you want to do. These can vary a lot and so it is well worth a look to see whether there is something that you like the look of. You will find that some sites have larger jobs and some seem to specialise in small jobs. Think about how much time you have, how much money you need and what sort of work you want to do and this should help you to pick the right site for you.
It is worth reading the terms very carefully before you start work on any site. You will find that on some sites you will have to earn a minimum amount before you get paid. Some people may think that this sounds like a scam, but it is not surprising that companies do this as Paypal has charges and if small amounts keep being sent out those charges really add up as there is a charge per transaction.
You should be able to find places online which will review websites which pay you to do work. It can be wise to check these out first so that you are confident that the sites you are choosing to work on are genuine and will pay you. This will take time and if you need cash quickly you may be in a hurry. However, it is wise to just take time for a bit of research or else you might end up working and not getting paid for it, which will be a complete waste of time.
You may find that there are some small fun things that you can do to earn some extra money. Things like survey sites, cashback sites and free lotteries are some examples of places where you can earn modest amounts in a fun way. These will not pay out so much money but they take no skill si anyway can do them.
