If these sites just go for some verification before promoting these scams, it would be very good for the visitors. Verification can include Mobile verification, Identity verification etc. These sites are an open image of crypto, if these sites just reduce their earned money by a bit and plan for long term then it would be beneficial for all of us.
There are some out there that promotes only those real project. It is just not as popular as those business platform. Still business is business in the end. Just give an enough money to someone they would be doing what you wanted. This literally happened as well on the outside world. Let us just hope for those who will be seeing those scam promotions be more aware and search more about the project they will be engaging.
