  1. Hi everyone. I hope you enjoyed this video. I will be watching the comments for the next couple of hours, so if you have any questions please ask them and I will try my best to help.

  2. Business Opportunity in Ruvol

    I have invented a Board Game [still unpublished and not yet out in the market] that I believe is guaranteed to be as challenging and exciting as CHESS. I called it “RUVOL.”

    It is my hope that one day Ruvol may surpass chess as the “Number One Board Game in the World.”

    The weakness of chess is it always starts in fixed positions that the opening moves become “memorizable.” In fact, not a few have so mastered the moves that they can play against their opponents “blindfolded.” It is for this very reason that the great Bobby Fischer introduced his so-called “Fischer Random Chess,” where the starting position of the pieces is “randomized” to make the memorization of openings impracticable. Fortunately, it is also for this reason that I invented Ruvol where “every game” has been calculated to be a challenging one to play.

    HOW IS RUVOL PLAYED and HOW YOU CAN MONETIZE IT?

    I detailed everything in my YouTube video. Here is the link: https://www.youtube.com/watch?v=jcqth0m3-R0

    BIG MONEY POTENTIAL IN RUVOL!

    It is worthwhile to note that the people who play chess will be the same people who will play Ruvol. In my Google search, I learned there are around 800 million chess players in the world. Even just a small percentage of these 800 million is good enough to earn big money from Ruvol either as an ONLINE GAME BUSINESS or as a PHYSICAL PRODUCT DISTRIBUTOR.

    Thanks and God bless!

  10. Hi Gary!
    Your article "What is a blockchain?" has some paragraphs doubled.
    Besides that, your article was as of now for me the simplest and shortest algortihmic and mathematical explantion that I found.
    Thank you!
    But one question remained for me: what is "mining"??
    The huge computational effort to generate the leading 17 Zero's for the hash ??
    Thanks for answering in advance.

  12. I have what I hope is not a ridiculous question. Would it be possible to broadcast a "blind" key, one that is meant to unlock some record or file or possibly an array of items from the broadcaster of the key without that key then being susceptible to association with items the original broadcaster of the key had not intended?

    I'm thinking here of a system that could validate the authenticity of public records, photographs, video, etc. The reason I bring this up is that it looks like we'll be facing a truth crisis at some point where it will be possible to so convincingly generate, say, video of a politician saying something they really did not say that even people who know them could be duped by the fake video. Doctored photos are pretty well at this point now and making the same reliable in audio isn't far off.With trust in the media already faltering, if this gets anywhere close to believable in video and we don't have a way to verify content from a broadcaster, it's hard to see how we prevent the fracturing of society getting out of hand due to there being truly no reason to believe any one account of events over another one.

  23. Such a good video! I was one of the early adopters of bitcoin back when the exchange rate was 1:1 for USD and I have never fully understood the blockchain until now. Amazing explanation, Gary! <3

  25. Hello Gary, please I am looking forward for the Kirin 970 explained or review. Because Huawei claimed it is a lot faster than competition. Will it be faster than Apple's A11 Bionic chip? It think it should, with 8 core CPU and 12 core GPU . Am not sure about the specs so am looking forward to see your video about it.

  33. why bitcoins are becoming computing intensive everyday??I mean earlier a weak CPU could generate many hashes but now even a high end computing device can't generate enough BTCs

    and who controls the value of BTCs??I know my questions are very basic but I am curious about it
