It's as good as any other signals provider.
Good for the initiators, bad for the ones who follow.
It works like this:
1. Initiators announce a pump.
2. They start the pump.
3. They tell their followers to buy.
4. Coin pumps, other market participants buy as well.
5. Initiators sell the coin.
6. They tell their followers to do so.
Result:
Initiators made tons of profit whereas most followers barely made a profit, and other market participants usually sell at loss.
Better stay away from such groups.
BPS influences and indicates every time they track a good pump but I couldn't say that they're that powerful because most traders don't depend on signals. They guide their followers just like other signals and tell them whether it's the right time to buy or to sell.
