Whenever I see this kind of threads, it makes me wonder. If you can make that much profit in one day, why on earth would you want to advertise the strategy?
If you can make even 100% profit, which is a third of what you claim, all you need to do is pump yourself 10 days in a row, and you will turn 100 dollars into more than $100,000. Why not just do this, be rich, and you never need to waste time again advertising and managing pump groups?
The answer is, it is most likely a scam. Avoid.
How is this a scam? How do we make that much profit? Really simple. You build a community of 500+ members. Have all of them buy a low volume/low market price coin at the same time, then magically the price of the coin goes up a lot. You take your profits and sell at the ATH. It's really easy but you immediately have a pessimistic attitude towards it because you can't do it yourself.
