When someone sends bitcoin to you, they send the bitcoin to your address. If you want to spend any of the bitcoin that is sent to your address, you create a transaction and specify where your bitcoin ought to go. Such a transaction may look like:
Introduction When someone sends bitcoin to you, they send the bitcoin to your address. If you want to spend any of the bitcoin that is sent to your address, you create a transaction and specify where your bitcoin ought to go. Such a transaction may look like: Transfer 5 bitcoin from 1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa (your address) to 12c6DSiU4Rq3P4ZxziKxzrL5LmMBrzjrJX (the recipient address). Of course, anyone can create a transaction that looks like the one above, so if it was added to the blockchain as is and without issue, then you would be out $30,000+ whether you like it or not.…
