  • So eventually the power/energy companies will merge with “big tech” companies and compete against one another. If Bitcoin were to become a mainstream currency, where would that leave your average civilian who has no chance mining faster than the aforementioned mentioned conglomerates?

  • Andreas I have thousands of bitcoin cash in my wallet on my cellphone and I don't know how to cash out. Please help….

  • Awesome! Can anyone recommend another video about bitcoin which is also as technical and as long as this one?

  • 11:35
    indeed, a8d19153 (a8d191538209e335154750d2df575b9ddfb16fc7) is the SHA-1 of "Hello!n", the SHA-256 of "Hello!" is 334d016f (334d016f755cd6dc58c53a86e183882f8ec14f52fb05345887c8a5edd42c87b7).
    The guy from the public executed shasum without params, which, nowadays, uses sha1 by default, the way to obtain SHA-256 is through sha256sum or shasum -a 256. Apart from that, without cleaning the new-line.
    The way:
    $ echo -n "Hello!" | sha256sum
    or
    $ echo -n "Hello!" | shasum -a 256

  • I may not have gone to college…but i have really invested in my education. This video is gold and is blessing to have available for free! Thank you

  • Watching this in 2019 wishing i saw it in 2016 . I invest everything i make into Bitcoin and other cryptocurrencys because i know what there truly worth ! Thanks for the awesome speach man !

  • Pretty neat! Andreas. I mined bitcoin in 2013 for money without knowing what I was doing. I left the industry only to return in 2017 – I've spent last 2yr watching videos like this! I know know better. I wish I watched this before I became a BTC miner…Very good!!

  • Hi Andreas, interestingly you mentioned the plan to increase the block size in 2016. I wonder what's your view of bitcoin cash and bitcoin cash SV?

  • Dr Andreas me perdoe e algo fiz centros supletivo s com problema de saúde deste criança são estudos………se formar desocupado e algo sério livros dor cabeça ética segurança saúde costas peso desobediência e perto portão rua como chá ? Pede pedra sopa receita.😍 Hoje como pessoas com perdas de espaço aceita café?

  • Andreas is a true genius! One can easily detect that, not from his deep knowledge on the subject, but from the humility with which she shares it with others! Standing applause!

  • Mac Terminal:

    hasum <<< 'Hello!'
    a8d191538209e335154750d2df575b9ddfb16fc7

    shasum <<< 'Hello!0'
    0e0978c3bcd55ccb10ef61aa900adee01c512d5e

    shasum -a 256 <<< 'Hello!'

    shasum -a 256 <<< 'Hello!0'
    7460100bc6dcc237f60b0b47c27c731ea41b64fb5462e2e4c2dd33d5f57f7fe9

  • Watching this in 2019 gives me a real feeling of how tech evolves! This was recorded when BITCOIN CASH was still a theory without a name yet, we have two bitcoin cash now! lightning network was still alive only in theory, we have payment channels funded with 1 BTC currently and still growing! Truly bullish on the future of crypto!!💯
