bitcoin's supply is perfectly inelastic. It's not possible for it to be negative.
And oil itself isn't negative, thats just a futures contract. you have to take delivery of that -$37 oil. 1000 barrels. They are basically paying you come get it.
Great comment.
But, look at the conditions I highlighted. What if those conditions were to be true, then what'll happen?
If there is no demand for bitcoin, then the inelastic will be forced to become elastic automatically.
If there is no demand for Bitcoin, then the value will hit zero. It will not go lower than that. You aren't paying a rent for your wallet, are you?
Are you referring to these?
1. A ban in the demand for bitcoin and a ban in the use of bitcoin.
2. Backing off of bitcoin miners from the business of mining?
1. That ban has already taken place in the past and even until today. Bitcoin is still sticking around, right? If in case each and every country in the world bans the buying and use of Bitcoin, that does not necessarily mean Bitcoin will hit zero or a negative value. The online universe is as wide as the real universe. People can do as many things there. The good thing about Bitcoin is that a ban will remain just a mere word people can easily dismiss as nuisance. There is nothing to shut down really; there is nothing to padlock; there is nothing to takeover; and so on.
2. If every single miner is backing out, then Bitcoin becomes useless, zero in other words, but not negative. But whether it happens in real life or not is a different story altogether.
