Hi,
I am quite new in this and have one question. If my father send me bitcoins to my wallet and i use it for deposit on neteller site, can my father see that i use it for deposit there?
If you don't change the address (using a mixer for example) he can know that you spent the funds but he wouldn't know exactly where because Neteller uses BitPay and they generate a new address for each deposit. (this is not valid for all websites).
