My point of view is that your question is realistic and we can go more high of this price but like as you said; that is, "some day" which we don't really know because the international juncture would send the price to skyrocket in a short period of time. As we have seen several times in the recent past, the price rises quickly when there is economic instability affecting several million people for a substantial period that is, when there is increased need for safe haven. Hence, if we see again these conditions in the global environment, then the price of bitcoin will cross higher than you believe.
