To date frankly speaking nothing, because I have never used my bitcoin. I think my bitcoin are my assets, and I want to earn more and more and increase my assets while holding it. And If I sell or buy something else with my bitcoin, it means that it will empty my bitcoin wallet, and I will never want this on any cost. So I have bought nothing and will buy nothing. I will just hold my bitcoin.
Same here, I kept my bitcoin for a reason and I'm not spending a piece of it. I mean look at how much its worth now and a year ago, the difference is huge.
