That logic applies to any currency, not just Bitcoin. How someone accumulates money is by offering a compelling product or service that saves people time and brings value into their lives. If a few people accumulate the most money over time, then they obviously deserved it. For example, I believe the richest man in my state of Florida is Thomas Peterffy, the founder of Interactive Brokers. That wealth didn't fall into his pocket out of nowhere, he earned it. IB has brought a tremendous amount of value to the financial marketplace through a variety of services, and the marketplace has decided that Mr. Peterffy deserves the wealth he has accumulated. Never forget...
Life doesn't give you what you want. It gives you what you deserve.
