The dash hash rate says it all. There are about 10'000 miners working on it. This is September + October batches so far. There will be 20'000 miners at the end of 2017, unless more batches come forward. Profitability will be about 10-12$/day at current dash valuations. Not bad for a 1450$ miner.
Those who want to buy the A5 at $10K are welcome to shoot their foot.
by my calculations there will be more then 50k miners at the end of 2017 and most of us can shoot themselves
