I think if it reaches the $500 mark then some people will start to off load a percentage of their BTC.
This might cause a dip next week.
Dips in the market are to be expected. More so once we cross certain barriers. However, the rate at which bitcoins price is rising, those dips will hardly be noticed. I find it hard to believe that with the rate of growth someone with large holdings would start selling off. At least for now. You may see noticeable dips once things start slowing down.
what do people here think about the CoinValidation concept?
I think as a external party tool/plugin, it would be good. As a requirement of the core bitcoin protocol, it is a terrible idea.
Interestingly enough, if we did have this, we could all avoid buying those coins seized from SR, and they would effectively be worthless.
What would be gained from blacklisting the seized coins from SR? Someone, somewhere would still be willing to accept those coins. What if those same people decided that the coins in your wallet should be blacklisted because of the taint levels from previous bitcoin heists? Suddenly all the time/money you've put into bitcoin will be for nothing. Sounds like a great addition to the bitcoin network.....
