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.
The telegram group that invites you suddenly is a scam, the real pump group will not invite people carelessly.
