No, they are not worth it. Don't waste your money with any of those. If you want to make profit with altcoins then just start trading. Don't be like those people that are into quick money because getting involve with those is going to put you to the bad side and even drag you to being scammed.
So many people are being scammed by bitconnect and this time it looks all of bitconnect creators have already arrested by the regulators.
Nothing new and the same schemes that are rotating not only in real life, not only with bitcoin but also with altcoins. They are everywhere and they are the scavengers in cryptocurrencies that are looking for newbies that doesn't have an idea about their scam strategy. But today, most of those schemes are already exposed and I think investors should be responsible and needs to reearch before investing.
