Some of us could hope for a bitcoin value of $400k it is probably years off. There are a few drawbacks if the fee situation is not handled by then.
I am considering the short term goal of first reaching 10k. All such superficial values always looks good to read if it reaches anytime in 25 years also. But the fact that till then things would definitely change and many more obstacles and hindrances would come by then. So lets go step by step to achieve the decent price of btc.
25 years is a long, long time. Some of us might even be dead by that time. Unless you are planning for your retirement, or you are an institutional investor, you cannot look at a 25 year horizon. I am not saying that try to double your money in a year, but maybe you should look at a 5-10 year period. If you Bitcoin will rise substantially in this period, go for it.
