Bitcoin is a highly secure way to make online payments. It's important to remember that bitcoin transactions are one-way, so once you give your money away, you can't get it back!This is not the same as payment protection with PayPal or our credit cards, however it does make bitcoin more secure.Another method for conducting transactions is to utilize a unique wallet address for each transaction. You have a reasonable amount of online anonymity by using a different wallet address for each transaction.
