welcome back chodpaba! it would be great, if you start sharing your information again! u can take much more profit while doing it ;-)
If I wanted to manipulate the market with that sort of signaling I totally would. But I don't think it is the best thing for the health of Bitcoin exchange markets, and I'm not that interested in the short game.
An increase will only get attention if it goes up and stays up. If it shoots up everybody will just respond "give it a week, it will be back down". Manipulation is not how we get to steady valuations above today's prices.
