I'm asking because I don't want to step out and walk away. Not only have I invested a lot of my savings into this technology, but I believe in the technology and the positive impacts that it can give to the whole world. There's been countless bad news since I started getting into Bitcoin, and recently, there has been a lot of good news, but the prices are still going down... I think for me, if doesn't get the right recognition/acceptance/price by the end of the year, I'm out. Probably keeping one BTC, but mostly try to get back what I spent.
Don't get me wrong, I would love to be in this for the long haul, but if I've already lost enough that it would only lead to stress and financial problems, I'll be thinking twice. Right now I still believe in Bitcoin, and it sucks that most people are ignorant and disregard this new technology, and its hurting us.
So what is it? What is you're "I'M DONE" sign?
Keep in mind that you have not lost anything until you sell. Market price is irrelevant if you are prepared to hold for a few months.
