Emin Mahrt

I've started mining pre ASIC time and bought the first KnCASIC Miner in 2013. Did arbitrage between MT.GOX and BTCE until MTGOX got hacked. Born and raised in Berlin i experienced to founding and fundraising of Ethereum (mainly from Bitcoiners) and spend most of my time in Room77, the first place in the world selling Burgers and Beers for Bitcoin and hosting weekly meetups, including the first Bitcoin Lightning conference and lightning transaction ever from Roasbeef (Olaoluwa Osuntokun). Early on i participated contributing to the first GUI bitcoin wallets, after the terminal time was over. During the scaling wars in Ethereum (Crypto Kitties) many people where looking for a faster smart contract protocol so i experimented and worked on a bitcoin-ng version proposed by Emin Gün Sirer called aeternity, and contributed during my time in Liechtenstein to several open source foundations and the Blockchain Act, later passed by the government. I worked as CPO at BSDEX Stuttgart Digital Exchange to help build the first regulated exchange in Germany. My passion though was always in self-custody, especially hardware wallets, such as the production of one of the first biometric nfc smart cards for Bitcoin with Konai from South Korea called Cryptokona. Living on Bitcoin since 2014, I always engaged in p2p exchange, but also regulated payment rails from Bitcoin. Bitwala, later Nuri.com, tried in 2021 to built a Crypto Friendly Bank, shut down in 2022 due to custody risk from celsius, and i bought the brand. Since then I dedicated myself to bring simple secure Bitcoin self-custody building the first bitcoin multisig smart passkey wallet that connects to several banking rails and is available world wide as web-pwa, ios and andoird app.
