I don't think so, it's just going to happen that Bitcoin won't be ideal for payments but still the best store of value.
Just a question, how can be a highly volatile entity be the best store of value?
What do you describe Bitcoin? Do you hold it as an investment? If so, then you're considering it as a store of value. Or, this is my take about Bitcoin for being the best store of value because this is what I've got. The other store of value, I don't have them and that's why it is the best for them. Thus, we're in a Bitcoin forum that makes every person here anticipate that they're also in Bitcoin but we've got different thoughts of how it is for being the best or not.
