Great questions! Once your change has been invested into a crypto such as bitcoin it is very easy to sell or send to your own personal wallet. You would just go on coinbase and sell/send it! The standard coinbase fees, coinflash does not charge any extra to it. They also just added a great new feature where you can easily turn your bitcoin/ethereum/litecoin into any altcoin of your choice.
