Well, I think that Bitcoin (BTC) is not useless. I know that the price is fluctuating but it will definitely increase. The price will not utterly go down to zero because a lot of people have invested in it. Though the value of BTC (Bitcoin) may fall, but it will still grow!
Yes, I completely agree with your opinion on this project. Bitcoin is not useless instead it is a most useful thing right now. Because of its current price, you think it is useless, but bitcoin is volatile, that's why its price consistently changing. Right now the price of bitcoin is low but it will definitely increase after some period of time.
