Usually paying with processors is ok as they fix a price for like 5 minutes to make your payment.
1 Bitcoin is still 1 bitcoin only for long term investors but for traders I don't think so, people will always look at the value of USD. Or people who use bitcoin as payment method will also always get annoyed when bitcoin price fluctuates and that's also why I don't like to use bitcoin as payment method. Honestly, I like the volatility of bitcoin if it becomes stable maybe more investors will leave bitcoin and me too. We are here to make a profit, when there is no profit people will leave.
This is why people do prefer on moving prices because we cant really deny that volatility could really make out some money and on the time that we would be seeing its stabilized price then this is where
people do lost up interest and would find out another things which is volatile because we cant really deny that we are really that interested into something which we can
make money and into something that we wont then it is really something that turns off.
