Receiving notification of a payment is almost instant with Bitcoin. They have facilities in Iceland and Georgia. Every day, more businesses accept bitcoins because they want the advantages of doing so, but the list remains small and still needs to grow in order to benefit from network effects. So, if a blockchain chooses to disadvantage brick-like ASICs by changing its proof-of-work hashing algorithm, they become as useful as good-old mortar bricks. Is Bitcoin useful for illegal activities? That can happen. There is a wide variety of legislation in many different jurisdictions which could cause income, sales, payroll, capital gains, or mining alt coins profitable mining profitability bitcoin other form of tax liability to arise with Bitcoin.
