I love electrum as bitcoin so i am going to use electrum version of super bitcoin. And the link that the dev state is
http://www.sbtcelectrum.org/ and not the one that you gave. So be careful on the authentic.
SCAM. There is no linking to this wallet on the official website. Plus, why the fuck would they make a new webpage just for 2mb wallet. how about you pm me your private keys instead, i will send the sbtc to you after that.
