My best advice always will be for us to always research these investments opportunities before venturing into it whether it's bitcoin related or not because this is the fastest way people are being defrauded of their hard-earned money today. People sit somewhere to say things which are unrealistic, from saying they will give you 10% ROI for so so time, to 5% from so so time, and they use these lucrative figures to deceive people and take their funds from them. I'm usually unhappy about these kind of Ponzi schemes because it's really heart breaking to see someone who's trying to make a living being swindled of their sweats in the name of securing an investment plan for them.
I'm always skeptical about all these form of investments where private investment platforms offer xyz benefits and plans for investment, even after doing one form of research or the other, I'm still not comfortable about their stuff. I rather don't engage in all those kinds of investments and engage in the likes of DCA as alternative or even lumpsum on existing CEX than on mushroom companies like the Paynet Coin Ponzi in Vietnam.
