What if the main selling-sites would sell mBTC instead of BTC?
1 mBTC = 5$ (there would be, imo a lot more buyers)
than
1 BTC = 5'000$
Actually, that would make it much better, as some Exchange are cutting decimal places or only allowing 2 -> 0.01 BTC
That will be a problem in future an in case btc will reach >10'000 (what will happen for sure

)
