It's easier to spend Bitcoin as money when the value is low, or maybe in a bitcoin bear market than when the price is high, to them it's very inconvenient to do.
Every bitcoiner will regret about their early spending of bitcoin and I am afraid that this trend will continue even for next 50 to 100 years as well. Because, bitcoin will keep rising on its value at least for next 100 years. Remember the famous 10,000 bitcoins spent for just 2 pizzas? When people are gaining more confident about the future of bitcoin like bitcoin may value 1M or 10M or 20M then I guess they will become a true long term holders rather than trying to cash out on small profits like a trader.
Do you also accept BTC payment? What's the experience between a bear BTC market and a bull BTC market?
I accept payments in BTC for my freelancing works and I do not spend bitcoins as I am a true long term holder. I have spent bitcoin in unavoidable situations but when I have fiat and bitcoin, I will spend fiats.
