I think bitcoin is not the best option in reality although it may be the best option in theory. For one thing bitcoin is still too easy to manipulate. I think the price will fall not to 18,000 but 15,000.. I think its worth less than that but i dont think the market will let it fall beyond that for reasons other than use.
The other part is bitcoin was an accidental store of value. It was designed to be a currency which has the capability of spreading more economic prosperity around the world. However it failed at that tremendously so they then scrambled to figure out what to do with it.
The problem is that this is a software technology that occurs in a space with no dimensions. So that basically means if you wanted to actually create the best store of value in a manufactured economy and not a natural one. Then you'd start from the inception to create the best store of value crypto not one based on an accidental creation. That wouldn't be an optimized system. A system that depends only on network and brand effect is not enough.
So now there are better store of value in the crypto space better than bitcoin. In the future there will be better models. Bitcoin will face a logical conclusion through deductive reasoning of challenging its very position and it will fail in that. The reasons currencies have value is because of acceptance and use. Bitcoin is a cryptocurrency. a crypto "currency". if it's gold 2.0.. there are so many things that can work better. There are so many creations that are optimized to do just that.
