After my saving reach 1-2btc, i get some prblem in my real life, then i sell my bitcoin..
That's really interesting as I had the same problem with my fiat savings before I started purchasing Bitcoin. I would see a certain amount in my savings account and then start thinking about all the ways I could spend it. Once I started purchasing Bitcoin I saw it as more of an investment and it fulfilled my need to buy things since technically I was "buying" Bitcoin. This investment in Bitcoin for better or for worse has drastically reduced my spending on unnecessary things.
