Few days ago i added by someone into crypto pump channel on telegram. They claimed that recently they have done many pumps and all pumps were successful done and on 29th August they were about to create huge Pump on binance. But nothing was actually happened on 29th. I lost around 0.04 BTC in 5mins.
So guyz be aware of these kinds of channels.
I think whales have their own network, and don't need anything except big capital. But indeed they might make the telegram team to make more optimal plans. But I think a good moment is more expected than careful preparation, because crypto is very dynamic, and anything can happen in minutes.
