Depends, am I still smoking? Darwin was what finally cured me off cigarettes, for me it is priceless. I vaped a year before I purchased the darwin, still smoking throughout the year. I even quit
vaping entirely and went back to strictly smoking. When I received my darwin I no longer craved a cigarette. Times were different then, there wasn't
rba's. We had cartos and atties.
Though to answer your question, I have no plans of selling either, but the ELA would be sold before my darwin would ever be sold and yes I could gain more profit off the darwin, if I were one of those types. I still use my darwin every so often.
Each person is different, you have to find what works for you. If you didn't have the problems I had while I was making the transition then my path probably would not apply to you.
