If Satoshi Nakamoto tell the mysterious truth about his Bitcoin and Blockchain invention and all the secrets to the media, how will it affect the Bitcoin Price ?
If someone just prove himself as satoshi nakamoto by signing a message with bitcoin address that are supposed to be of satoshi, it will be enough to create so much panic in the market which may lead to massive price dump due to fear.
But why? what's the reason behind your statement that said if satoshi reveals himself then the price will be hardly dumped? how if the thing goes the opposite and bitcoin hardly pumped?
Your statement that saying the price will be dumped is just unreasonable and pure speculation.
The price indeed could decreasing, but only if satoshi does something which may really affect bitcoin as a whole such as selling his bitcoin at a sudden.
