Thank you,
Sir, for the accessible lecture.
I love the grounded reality of this channel, its normal to see so many investors panic amid a worsening bearish market but it is also important to note that the market situation is nothing new in the crypto world. Several factors are driving negative sentiment in the stock and crypto markets right now including inflation, a shaky stock market, rising interest rates, and recession fears. As a result, BTC has dropped significantly from its all-time high, breaking below several key technical levels. As a crypto investor, the current situation might seem bleak. However, there are several tried and tested expert suggested investment strategies that can help you accumulate the current crypto storm, in few weeks of implementing trade with accurate signals directly from Theo Ryan, I have been able to accumulate over 19.5 btc despite the current state of the market.
Thank you so much for this enlightening video it has helped me greatly. Many a time new comers are indecisive on how to start when it comes to their personal investment growth. But great investors can provide proper guidance…
How rich would Satoshi be,if he mined 90% of the Bitcoin supply?

BTC is the future of finance. Most traders ask themselves is this the right time to invest? yes before jumping into conclusion I think you should take a good look at things first. for the past few days the price of Bit coin has been fluctuating which means the market is currently unstable and you can't tell if it's going bearish or bullish while others still continue to trade without the fear of making lose, some are being patient. it all depends on the pattern with which you trade and also the source of your signals. I would say trading has been going smoothly for me. I started with 1.9 BTC and I have accumulated over 11.6 BTC in just few weeks with the trading strategy given to me by expert Mrs Beatrice.
anyone knows: are all coins are immutable? thanks!
More Qeustions:
@23:48
– How is the data from in a tamper-evident log stored? In a key value store? Since you are not using pointers to memory you need an auxilary store right?
– Does the prev H(arrow) include the prev pointer AND the data or just the data? It would make more sense to include both right?
Typing out my questions as I make my way through the video… I'll probably be posting multiple times…
– When discussing the commitment API around the @14:28 mark, why do hash the 256 bit key? H(key)
– Is it because we do "H(key | msg)" and theres some sort of communitive property?
– Is "binding" essentially the same as saying the hash function is collision-free (impossible to find collisions)

I think the pandemic has taught people a big lesson, having one stream of income is not really a good idea cause your job doesn't secure your financial needs. The pandemic has really set out business-minded people from the rest that is why I'm so lucky to be among the investors trading with metro__kelvinfx on insta as his student it's been success and happiness since the beginning of my trades
X'R'P, contrary to popular expectations, has recovered well since the SEC-filed lawsuit forced the altcoin to fall to $0.28 on the pr!ce charts. In fact, ‘recovered’ would be an understatement, especially in light of the altc0in’s rate of growth this year. What’s more, it can even be argued that the aforementioned lawsuit was what fueled the pump in X'R'P’s value. X'R'P climbed by 32% in 2 days after Ripple execs filed motions to dismiss, following which, the alt followed B'T'C’s lead to depreciate by 28%. Despite the scale of these corrections, however, X'R'P, was noting YTD returns of 448%. X'R'P’s indicators were leaning towards the market’s bears; however, a trend reversal hadn’t prevailed completely. While the Parabolic SAR’s dotted markers were over the pr!ce, RSI was fairly close to the overbought zone. I always tr@de daily with Mr. Vincente Sanz's trade s!gnals and the result have been stunning.

Never knew trade could be so challenging! Kept running back to these YouTube videos to learn more about this your video is indeed helpful. Thanks
The federal authorities will likely soon begin enforcement actions against taxpayers who have failed to properly report their virtual currency transactions. But institutions and entities in the virtual currency industry are also at risk if the IRS believes they facilitated tax fraud. For example, the IRS may assert that an employee of a virtual currency vendor improperly told a customer that taxpayers need not report virtual currency transactions on their returns.
