I think not need to have bitcoin as a way of payment. you can easily change bitcoin you in the form of USD or whatever your local currency with the help of exchanger and then pay to the buyer. why limit yourself just by attached bitcoin. you can continue to get a wealth also and stay spend on the same level and it gives you all the freedom of you want. it doesn't matter if confirmation bitcoin slow or anything. when you submit bitcoin, you can not really refund the payment that buyers sure that it will get the money. also, you can negotiate cost and ask for buyers to pay a half and you will pay for half of the confirmation will be more quickly.
