Selling your bitcoins against your plans means you are giving up on your dreams, especially if you never thought about making money from such a volatile asset. Selling BTC does not give you the desired gain and it feels like losing your money all over again.
I'd love to know more about your plans, and how you're planning on meeting them. What will you buy with your earnings? How will this affect your way of life?
I see it as a business decision. I knew that bitcoin was going to be big, and I built a plan to profit from it when it happened. So I sold my BTC when they were $9,000 per coin and made me a millionaire in only a few days.
Selling my BTC against my plans (for now) to discipline myself on not spending in the moment is really helpful to me. I was able to sit down with my wife and explain that while we dont count every penny, I needed to begin thinking about what I had spent so that as a family we could find a way to pay down debt. Once there were zero unspent expenses for the month, I knew that I was well on my way to being debt free.
