Yes I use bitcoin as a currency for buying some goods and in game goods in bitcoin accepted stores
and I store bitcoins for investments and also for future purposes.
Well, I also sometimes use it to buy something. so many people who see bitcoin as a currency and as an investment tool. I also saw bitcoin as both. I guess because bitcoin really has that potential. but the best thing you can do bitcoin is as an investment tool, because with that advantage, so many people using bitcoin as their livelihood
In my mind, I am thinking that I use bitcoin as an investment but what I actually doing is using it as currency - I usually exchange only 2 cryptocurrency: bitcoin and doge. I sell doge for btc when doge is high and I buy doge with btc when the doge price is low - my profit is the difference of high and low price of doge.
