Bitcoin & Blockchain for Friends


Published on

On the 15th of November I spoke for my favourite audience in the world, friends and family! Ever since I became a speaker on Bitcoin and the Blockchain, some of them have asked me when they could attend a presentation to see and hear what it is all about. So I decided to host something myself and some friends invited their friends too. I had a great evening, thanks everyone!

 why isn’t everyone using it? @SDWOUTERS
  97. 97. @SDWOUTERS ‣ Bitcoin is only 7 years old, it still needs a lot of development.
 ‣ We have never tried THIS before and it is about MONEY, not info.
 ‣ It’s like the Internet in the 90s: 
 ‣ People don't get it. ‣ It looks ugly. ‣ We have few use cases. ‣ People don’t see how it will change the world. ‣ Those who are disrupted by it will do everything to stop it. ‣ Mainstream 10 years later ‣ Mass adoption 20 years later
