If I sell my bitcoin, will that put me in a higher capital gains tax bracket?

Currently mt husband and I make about 76k. That puts us in the 0% capital gains tax bracket. If we sold a bitcoin right now we would profit approximately 70k. Would that put us in the 15% capital gains tax bracket?

On another note, if someone transfered a bitcoin to us and we sold it, would we have to pay short term capital gains tax?
