I have never been frustrated with bitcoin during my time using it. I find bitcoin to be profitable in all forms compared to bankers. Sometimes frustration happens when I experience huge losses through gambling.
Yes qe just experience frustration when we are losing it. I experience it when I got scam here. But after that experience I never get frustrated again because I find it helpful in my financial need. Bitcoin was a good thing that Iam thankful to discover it. Because not all people in the world new it and experience the benefit that you might get from it.
