Riporto quanto scritto nella
descrizione breve sul sito della Bitmain riguardante l'S1
"In the next few days, Bitmain
will adjust the price of the S1 miner on a daily basis. We will reflect the shipping date difference, which means every time our website store manager deliver the order information into the shipping system at the 18:00PM of Beijing, the price will be adjusted. So please don't be upset if you buy the S1 then only 1 minutes later the price dropped a little bit. It only means that you have caught today's last bus."
