So this ID what does it say? like?
I dont get 1 thing. People put their btc addresses all over the net asking for donations which are basically like putting address and sending. And in my case we just resent btc to my address so why the hell i could not receive them?? WTF pls some logical explanation
First off, you are not going to lose anything.
Sending coins means you create a transaction, which then signs the coins over from one address (your sister's) to another (yours). This signing over only happens if the transaction is included in the block chain. If you did not include a fee (some client sadly do not do this by default), the miners who create the block chain, may take longer to include your transaction, because there is only so much space reserved per block to include transactions without a fee. Over time, the priority of your transaction increases and it will be more likely that it will be included.
Worst case that could happen is that the transaction is not included and the network forgets about it. In this case, the coins would still be in your sister's wallet and she would need to resend them to you (this time possibly with the minimum fee of 0.0001 BTC).
i'm assuming, since the OP isn't very good at handing out info, that his cousin doesn't have the BTC left in the wallet.. which is why he's so concerned. it could be that it wasn't sent out, and is st ill sitting in the wallet.. but i'd figure that he's smart enough to check his cousin's balance.
