There are huge speculation that if Satoshi Nakamoto reveal his identity and sell his Bitcoin then the Bitcoin market will crash. This is nonsense propaganda by few Bitcoin community leaders.
When Satoshi Nakamoto will reveal his identity, he will get a Nobel Prize in economic science, he may not need to sell his bitcoins at all. Even if Satoshi Nakamoto sell his Bitcoins and donate to charities, it will not affect the Bitcoin value. When he will get a Nobel Prize in Economic Science there after hundreads of millions of investors will buy Bitcoins. The Bitcoin price will hike and go to the moon. That is my prediction.
Satoshi Nakamoto is a benevolent Economic Scientist and he deserve the recognition for his work.
You cannot even imagine the amount of trouble he will have coming for him. Bankers, regulators, politicians and other corrupt demons are going to ensure that he commits suicide by two shots at the back of his/her head.
Its best if Satoshi stays anonymous forever. There is absolutely no worry about him/her selling his/her Bitcoins. Sure that will cause a dump. But his entire Bitcoin holdings is a bit higher than 5% of the market cap of Bitcoin. So the dump will mostly be caused by speculative panic. And BTC will heal over time. Maybe even instantly.
Bitcoin works. Thats why we believe in it. Its worked for years now. And nobody has been able to prove it as redundant.
