Nobody is going to make a professional exchange for BTC.   At the hype-peak of ~33USD the entire "market cap" for BTC was under 200 million dollars.   That's less than the commission a goldman-sachs type institution makes on an average deal.

All the pro-markets have billions or trillions in volume.   With the micro-scale of BTC, you're lucky to get Magic: the Gathering nerds to break financial laws to exchange for you.   I've yet to see anything AT ALL in the entire bitcoin ecosystem that isn't rank-amateur.   From the hilariously basic scams to the mining pools to the exchanges, it's all done by people with no experience in these things.   Even the design of BTC itself suffers from serious naivety in financial matters - an inherently deflationary system can't grow.   Even if (and it's a big if) the exchanges manage to keep going, as the mining rewards dwindle to nothing over the next two years and more and more BTC is lost to deleted wallet.dat files, where is the currency going to come from for new entrants to the market?  Every new good will be chasing scarcer and scarcer BTC.
