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?
No, your father will be able to know that you have transferred your Bitcoin to another address (with the help of blockchain explorer) but he will never know that you sold it on an exchange or other people because it doesn't always mean that when you transfer your Bitcoin to another address you already sold it, it can also be you are just transferred it to another address because you want to change your wallet or address. Blockchain explorer will only let you know the address where you sent it but not the identity of the owner. So yeah, he will never know unless you told him that you sold it.
