This will continue to exist but if we do not support them, they will not be successful of scamming the majority of investors, there is no law that governs bitcoin so they can do whatever they want.
to be honest I wouldn't call them "newbies" instead they are idiots who are also desperate enough to think they can make money this way. HYIP is a scam, and we all know it and anybody who stumbles upon them for the first time figures it out too. but only those who don't use their brains think they are profitable.
all these strategies of getting in first, .... are delusions of these people. they are gambling with terrible odds of winning.
It worked in the past with real world scams and pyramid schemes because they required a lot of effort and initial investment to start up the whole business. That's the reason why first "investors" could actually earn something through them, else the operators would be at a loss if they ran away with their money without delay. Today you don't need a lot of investment, and you can close the business in a matter of a few days, after receiving some money.
It really happens before but now ,in new generation people were more smarter we think most of the time if its scam or not because it is the trend the story of getting scam. Now we learned already our lesson to research before doing. In this way we can avoid getting scam. And be profitable in investing.
