I've spent the last year bank-free. I live in the US, but work for a Swiss software company and get paid the CHF equivalent of $160k/year. They pay me in Bitcoin. I have no bank account. Everything I need to buy I either pay for directly in Bitcoin, or in cash. When I need cash, I use LocalBitcoins to find somebody who wants to trade. The "massive bureaucracy with its bloated laws and indifferent employees" can fuck off. They can point their guns at secp256k1 all they want but it won't do them any good. I just have to laugh at people who still care about or participate in politics - it's a complete waste of time. Within a few years Bitcoin has accomplished the change which many decades of voting have failed to provide.” - Wonko the Sane, Slashdot.org, 2014-10-26 2014-10-29 - Luzius Meisser – Bitcoin Association Switzerland 10 Specialized Hardware ATMs Trezor Wallet Coins & Notes Mining Hardware 2014-10-29 Luzius Meisser – Bitcoin Association Switzerland 11 12 Mining Bitcoin network speed more than 1000 times faster than top 500 supercomputers combined 2014-04-02 Luzius Meisser – Bitcoin Association Switzerland 13 2014-07-03 - Luzius Meisser – Bitcoin Association Switzerland 14 Bitcoin in the media «Wenn die Bitcoin-Blase platzt» - 5.12.2013 «The rise of Bitcoin» - 4.7.2013 «Bitcoin Fever: The World's Largest Online Currency» - 21.3.2013 «Bitcoin Is A Disruptive Technology» - 9.4.2013 «Die Internetwährung wird salonfähig» - 12.4.2013 «Bitcoin wird Thema im Bundesrat» - 9.12.2013 «Is Bitcoin the future of currency?» - 11.6.2013 «Why Bitcoin Is Being Taken Seriously» - 27.3.2013 «Bitcoin – Virtuelles Geld» - 29.11.2013 15 Bank attention Q1 2014 2014-07-03 - Luzius Meisser – Bitcoin Association Switzerland 16 Legal: Federal Council Report Means of payment AML laws apply Only lower volatility missing to be considered money SRO under construction: dfca.ch 2014-06-06 - Luzius Meisser – Bitcoin Association Switzerland 17 Swiss Regulation London & Isle of Man want to become centers for crypto-finance Switzerland laws neutral SRO «digital finance compliance association» Bitcoin an opportunity for Switzerland? 2014-10-29 - Luzius Meisser – Bitcoin Association Switzerland 18 Swiss Franc vs Bitcoin Comparison Swiss Franc Bitcoin Must understand to use No. Who knows how ECCards work?
