All I know is what's on the site, next pumps on Tuesday and Thursday at 5 PM ET, so there's one today, on Bittrex. Two hours before the pump, the "Next Pump" page on the site will have the IRC client activated and you'll be able to join the channel through which the organizers control the pump. They pick 8-16 coins, number them, then the first hash of the newest mined Doge hash will determine which coin gets pumped. Once that's announced by the announcer bot, you quickly buy in and immediately set a sell price to an amount you think it might sell for. The way to do it is to be quick and not be greedy.
I have checked their site and it says you need to pay around 0.5 BTC to become a member to get the accurate time/date for the pump to happen, how come you join the pump without being a member there, Can you tell me more about how you got to get the pump details for free?
According to what I know and what I experienced, fairpumps do not have to pay for 0.5 BTC. I think it's too high to be able to join fairpumps, there are still many ways to get involved even though it's a bit late knowing which coins will be played in this event.
