If things don't change, I'm not sure if Evolve will continue in the vape market.
Why not? Their business model is a lot better for survival than Provape's. They sell regulator boards and software. I'm not sure where their actual chips (the ones on the board) are sourced from, but given the way components are made, my money is on overseas. The boards may very well could be (maybe they are already) assembled overseas. Third party vendors, mostly overseas, design, assemble, package, and sell the finished mod to the public.
Even if a single Evolv based mod was never sold in the US tomorrow, dna mods will still find homes in Europe, Asia, and elsewhere. Evolv software can be developed and hosted from anywhere. Yes, Evolv might have to sacrifice the hobbyist market by not selling individual boards to retail customers, and they might have to create a new model for corporate function to be conducted beyond US borders (hey, you don't have to relocate to China, nothing wrong with Bermuda and outsource assembly to China, works great for Black & Decker) but it's not the same as packing up a full on factory like Provape and moving to Asia.
Then again, if Provape really wanted to stay in business they could have relocated manufacturing outside the US. Still lose a bunch of US jobs, but if your business was profitable, it could have been done.
