How does it matter for seller of BTC? Once you sold it, it can be owned by anyone, how is it your concern? What's important is how many people own it. Not who exactly owns it. Today Coinbase/Bitstamp are doing good business by connecting people who want to buy BTC and sell BTC. As more people will get paid in BTC, more transfers will go directly from customer to employee without exchange intermediaries. But the real adoption does not depend on amount of transfers. That's secondary. Real adoption of money as money is in how many people hold it at every single moment of time. More people -> more demand -> more liquidity -> more value -> more trust.
