If you really believe that the value of Bitcoin will increase in the future, you will not take the step to use it as a payment online. Of course, especially if you believe that it will be $100,000 and at least one bitcoin. That means there is no reason to pay it. You are just wasting Bitcoin when you do this.
Although, at the moment, the price of Bitcoin is decreasing, I think it is possible that it will only drop to 40k and then go up again. So far, I haven't seen any breakouts go up or down too much.
