Bitcoin price has nothing to do with the blockchain. All market trading is done with imaginary tallies in a trading program. No bitcoins are actually traded from markets. They are only deposited and withdrawn depending on how well you play their trading computer game.
Useless post, talking about absolutelly other topic...
If you have a lot of BTC you can move the market
If you have a lot of BTC you wont keep them on Bitstamp wallets, you will move them to your own personal wallets/adressses whatever
If you want to sell a lot of BTC via "normal markets" you have to move them to their wallets (Bitstamps e.g.)
All moves are publicly visible on blockchain
People know, or are pretty sure which wallets belong to the biggest exchanges
What is that you do not understand in this simple case sherlock... :-( ?
Could someone verify what i said?
