op not this topic again, honestly this topic has been discussed severally and analysis intensively that your post is very basic compared to the many post on this topic already made in the forum.
Anything that concerns scams hacks and basically anything security be it for assets or your personal data is something I entertain every single time the reason is even if the topic is raised multiple times you can't directly call it spam since it serves as a reminder for those that may be careless and eventually fall for them.
There are some set of people who still see Bitcoin as a Ponzi scheme here in our country Nigeria, they believe that the same way MMM, CBEX and others crash that is the same way Bitcoin will one day crash.
The sum of it all is pretty simple run from anything that looks too good to be true. Invest X amount and referrals or complete tasks to earn money and withdraw xx:xx:XX are all MLM scams they wrap people in an endless chain circulating a token and siphoning the rest.
