Everyone himself disposes of his time, those who believe that this will benefit them in the future is not a pity to their time, and the others have long since left.
My reason to spend time in bitcoin is to became more porfitable soon, we all know that a lot of people who are spending with bitcoin now can definitely be very profitable when bitcoin rises again it's price. And when bitcoin can hit again $19k for sure a lot of people will be rich.
I take Bitcoin as the future of the mankind, thus, it is the part of my future as well. That is why it is great to spend time on BTC, investing in it, and trading as well.
