You get enough karma, a few downvotes always happens and it doesn't hurt as bad. I have people who follow me around downvoting me. Who cares. =)
ProTip: HN isn't looking for personal opinion on crypto. I'm not either for that matter, in either direction. That's why it is easy to rebuke the haters. They are so engrossed with their hate that they can't see that what they are saying is just repeated and boring trope. Easy to score karma against that.
