If you are really desperate for money then there could be some great ways that you can make some cash online. Getting the money immediately could be trickier though. You will benefit from having an online bank account with a company such as Paypal so that you can easily collect payments and then send them to your bank account. It is easy to do and does not take very long. This will then allow you to make money in all sorts of different ways, depending on what you specifically want to do.
Some people find that the best way to make money online is to sell things that they own and no longer want or need. This can be a good way of generating some extra cash and there is no tax due on any earnings because they are items that belonged to you. There are plenty of places where you can sell too such as online auctions, marketplaces and social media pages. It is best to search for similar things being sold, so that you can see where to sell them and at what price.
If you do not have things to sell then there are other ways that you can make money. You could do freelance work, for example. There are many sites where you can pick up work like this, small and larger jobs suiting lots of different skills. If you are a writer, programmer, artists, designer or something like this or have skills in this area, then you should be able to find work that would suit you.
There are other ways of generating money online which might be easier. You could answer surveys, watch adverts, play free lottery games or get paid to read email. These types of things tend to pay a lot less and it can take time to build up enough money to be able to cash out. This means that you may find that you will need to be doing these sorts of things for a long time before you can make a significant amount of money.
There are quite a lot of sites that will advertise that you can make lots of money, very quickly. You need to be wary of this because making money fast is difficult and the adverts and sites are probably not being completely honest. It may be that they will expect you to pay a lot of money in and you may risk not getting it back. It is worth being extremely careful when you are using any site to try to earn money. Make sure that you fully trust it. Look carefully at the site and make sure you understand how you will earn money, whether they will deduct money from you and if you have to invest anything. Find reviews of the site as well so that you can find out if other people use it and are happy with it and if they had any problems with it. Only use it if you are confident that you will get paid for your efforts.
