i know one person admitted that he made 1000 btc in two day of mining
but i want to preserve is privacy
also it is very naive from you thinking that bitcoin was not instamining when it is so obviously, no one know about it back then so the diff was without a doubt really low for a very long time, this lead to instamine
so I ask for proof and you have an anonymous person that you can't tell me about.

Again, your logic is strikingly poor. YOU CAN LOOK AT THE DATA AND SEE IT WAS NOT INSTAMINED. Just because there were less miners then doesn't make it an instamine. That is a genuine early adopter benefit. Nothing shady about it. The entire reason people don't like premines and instamines is the fact that they are designed to make a few people rich. In other words, they are less interested in viable currency and more interested in making money. Bitcoin was designed and mined fairly from square one.
Designing your coin to be mined at an absurdly high rate in the first few days in comparison to the rest of the coins history, like vertcoin, litecoin, primecoin, peercoin, comprises some of its integrity.
If you can't see the difference between these two scenarios, I can't help you.
