I am sorry, and not trying to be rude. One of these threads pops up every day or two with someone thinking they have found a new flaw in Bitcoin. You are as anonymous as you want to be. There are many options to increase this. here is a picture from one of the hundred threads about this.
Try to track that.
I met a guy at a Silicon Valley finance round table party. He says it is easy to trace that with a computer program. Even if you use a mixer, it can be traced if you make a mistake. For example, if you have a large amount of Bitcoins that you mix the Bitcoins in small batches, then, recombine the batches into another address such that the original address has the same amount of bitcoins as the destination address. There is software that can detect this.
I asked a legitimate question. Not finding a "flaw" in Bitcoin, but just want to protect my privacy when using Bitcoin.
Thanks.
