To recive $GRIN ツ cannot be more easier… you just need to make sure your wallet is reachable and provide the generated address to the sender. Some users ask themselves which address should they give? The simple answer is: you can use either one.
The first address: 54quafp5ug6z2akgflkynlaxwtdjhzytxrhk5q3gxptbaowvwliv32qd is used for sending via Tor. The second one: http://54quafp5ug6z2akgflkynlaxwtdjhzytxrhk5q3gxptbaowvwliv32qd.grinplusplus.com/ can be used to receive coins if the sender does not support Tor. In both cases you don’t need to worry about port forwarding.
Since my wallet is green I can receive my coins…
After a few the transaction will be fully confirmed and I will be able to spend those coins.
