Every bitcoin wallet gets a default bitcoin address. It looks like a long scary password and it will always work and never expire. Just copy it and give it to whomever you want to pay you and wait for the bitcoins to arrive. You can make a new address by clicking the “generate new bitcoin address” You can make as many as you want and use them anytime over and over if you wish. Once you get bitcoin it will inform you that you have “incoming bitcoin at 0 confirmations” It takes three confirmations before we credit the bitcoin to your balance. This can take anywhere from 20 minutes to three hours depending on how congested the bitcoin network is. We cannot help this and you must wait, once it clears three confirmations the bitcoins will be available for you to use. If you want it to clear faster ask the sender to use a higher network fee.
