I use bitcoin as currency and i never sell my bitcoin, but i prefer to use bitcoin when price is rising
So, how about you?
I agree that bitcoin is an investment, but before it became an investment it was first as currency. So i use bitcoin both as currency and investment. I use and convert a certain percentage for my monthly needs and then invest another percent of it to earn more bitcoin and grow it. So that I won't dried up of bitcoin in my stash.
Well to take bitcoin as a currency to a next level we should use it as a currency, as rotation of coins is important for the better future of bitcoins, as only holding will not help in long run.
If price gets stable then you cannot expect higher profits in future, people are investing their money in bitcoins only to take advantages from price fluctuations.
