Everything are just speculations.
There are no evidence pointing that they belong to Satoshi and even if it is
At least they doing it discreetly.
I won't be surprised if satoshi continued mining or his still a miner Even till date with him been alive been constant.
We experiencing a slight dip a minor pull back but the eyes is on the future not the now.
Don't get the mindset that you want to sell now and buy later at a cheaper rate even if your analysis dictates that.
I think you are right, and I also share the same sentiment with you bro, nothing is proven, till then I take it as mere speculations, because I know for a fact that Satoshi is not that myopic to be selling his Bitcoin so cheap, when he actually knows that this current price of Bitcoin is nowhere near it peak price.
Selling of a total of 24k btc at this present rate is way too much of a loss for someone as intelligent as satoshi to fall for, if truly this particular transaction are true, then I believe that it might be one of those early investors that got Bitcoin very very cheap, and he or she now feels like his target have been met, Satoshi wouldn't waste his current Bitcoin holdings like this, when he knows the true potential of Bitcoin and how much it can rise up to in the future, so am quite confident on that it's not Satoshi making such a wrong move.
