if i buy bitcoin with a paypal account and then change this bitcoin wallet to another bitcoin wallet and with that wallet transfer bitcoin with somebody paypal money on another new pay^pal account, can they reach from all where it all start or every thing is lost because it is crypt ?
Of course they can't, I mean no one would make an effort just to track someone's bitcoin on where it came from, and even though, buying bitcoin is not illegal on the first place, so there nothing to be afraid of, or have to worry about, because it is safe. What is wrong is if you are going to buy Farm accounts here, which is illegal, and if a DT or someone finds that it is just a Farm Account, then they would put a Red Trust on it, and the worst is you are going to get banned here.
