most people don't realize but it takes days/weeks/months for most forms of transactions to reach the bank account of the store owner, often with huge fees. (even paper money) and risk of chargebacks.
paper money also bears risk of robberies (and theft from cashiers, even though almost no cashier is stupid enough to steal) so most stores don't like being paid in cash.
not to mention the problems with change.
Bitcoin doesnt have any of these problems.
What are you smoking? Can I have some?
i can not imagine you are a business owner without even knowing the drawbacks of each currency.
you probably have a web-shop otherwise you would be familiar with the problems of cash transactions.
even still, a web-shop can benefit by bitcoin because unlike credit cards and paypal, bitcoin can not be charged back (so you're less likely to get scammed by your customers). and credit card payments are not instant, unlike bitcoin.
You can also get more customers by offering a discount, as the transaction fees are lower, thus saving you money for discounts. Transaction fees, especially for small transactions, can be quite hefty.
