Such returns are obviously NOT possible. Don't fall for scams on the internet (especially here on the forum, on Twitter or Telegram) which promise those unbelievebly high ROIs. If something sounds too good to be true, it probably is. If someone would know a way to make thousands of dollars in a few days, why would he share his method with you? Wouldnt it be better not to share it?
Conclusion: Dont fall for scams that predict huge returns! You will lose your money!
