Bitcoin Q&A: 2FA and secure hardware




How secure is Google Authenticator? What are some hardware two-factor authentication options? When will these hardware security options become cheap enough for frontier markets?

These questions are from the HoshoCon event and the Seattle ‘Internet of Money’ tour event, which took place on October 11th and November 10th 2018 respectively.

  1. Praying and hoping that an economic downturn alone will automatically translate into a rise of value in crypto is fallacious at best: Crypto as a storage of value has several major hurdles to overcome to actually compete and perhaps overtake fiat/digital fiat, credit cards and other traditional access to liquidity, loans & credit. Acquiring crypto, spending crypto and cashing out of crypto is far from being stupidly easy – and it needs to become "stupid easy" before we will see masses (and their transferable assets) migrate said assets from one system to another – case in point: silver and gold – hoarders and dreamers dying to see a zombie and/or nuclear apocalypse thinking that only precious metals will then allow them to buy fuel and bread while these assets skyrocket to the moon is just plain dumb – Do I need to remind everyone why this is stupid?!? Crypto, on the other hand, has real potential of establishing itself as part of a serious international trade system, however, building an easily accessible & usable transactional systems around this asset class is detrimental to the entire system's survival; Innovation is the key here which has not much to do with the downfall of wall Street: "Buy crypto because money is shit" is a very weak sales argument – Miners, Hodlers and crypto day traders do not help advance crypto adoption – but using and spending crypto with trust and confidence does help grow this tiny novelty ecosystem into the novel marketplace it needs to become – by proving itself superior (not by comparison) but by decree and trust.

  2. Fundamentals for crypto have never being stronger. The bullish case is in the "value" this new and different kind of asset represents and the little adopted and understood it is. The central banks of the world have not corrected a single aspect of what brought us the last financial crisis. If only more people comprehend the positive impact of sound money, sound money would be something desperately valued and hoarded. People is not moronic nor imbecil, only uninformed. how lucky I am to meet with such an experienced, honest, and hardworking, his working strategies are providing great results, if you have lost so much during fall or want to increase your portfolio like me. Yall can reach out to him through His HANGOUTS and Mail *decreetrading55@gmail. com ).

  3. What's that? There's a $20 hardware wallet? I thought I missed out on the Black Friday 50% Nano S deal. Now where is this $20-$30 Hardware wallet? Guess I can wait. I still didn't buy any coins yet. Guess I'm still waiting for this meltdown to finish. Thanks for another quick and honest vid.
