...Mostly, these "companies" are requiring it's users to refer people as much as they can. And they are claiming that they will pay their users for every referral they made. ..
A referral is a very common program done by many parties in order to invite many more people to join and register and do some tasks to the platform/website of the company. I also several times to join this referral program. But, some notes must be paid attention in order to avoid the scam referral. As we know, as the bounty itself, a referral may be also legit but maybe also scam. It is like the project, legit, and scam. The way we analyze and decide will really influence we are going to get it as legit or scammed.
They will not allow you to withdraw! (in the first place they really won't and they really can't). Because they are scams!
Most of them will require you to pay something "for you to be able to withdraw your funds". But once you do, nothing will change. You just gave them your money.
Everything if you need to deposit first in order to withdraw it, better to leave it. Moreover, if the reward is so high so that everybody will be interested to join the referral program.
Actually, there are legit referral programs that we can find, as what we can find on bounty or others. But you must note about these followings at least:
1. Analyze first the site or platform that offers the referral program. Are they trusted?
2. Never only becomes so desired and interested because of the high reward, but try to ensure that they are legit and not a scam. It can be seen from what platform. Personally, I always join the referral program from the popular and trusted platform that I have known that the reward of token or coin is really listed on the trusted exchanges.
3. Try to ensure that there is another way to cash out the payment without any deposit first to the platform. If you need to deposit first, ensure that the platform is very trusted if not, it is better not to join the referral program.
4. ANalyze also the mechanism of referral programs, many people don't read about the T&C when following this referral program so that they miss something and don't get any reward after doing a referral. I can say ao because I also join in several referral programs and they are legit but some people can't get the reward because they don't do some T&C.
5. Know the referral program, know the platform, know the T&C, know the reward, know the mechanism, know the profits, and never forget to know the RISKS.
please note that not all referral programs are legit/scams. It will depend on what platform/sites/companies. So, once more, be smart and careful when going to join such a program. Never only follow other people only. You must have willing also to analyze the referral programs by yourself. If you have often joined in the referral program, you must know how to get more people to join by your referral codes but not making them fool about the high promise.
You are right, No easy moeny, everything needs more efforts and analysis.
