Just imagine when Bitcoin is 150 years old, where its price will be and how many people will possess any Bitcoin.
I'm not even thinking Bitcoin for the next 50 years, the world is changing, so is the technology, we never know what's going to come next, I'm not saying there will be better than Bitcoin, but what we have now is something beyond our comprehension 40 years ago, I will just enjoy Bitcoin in my lifetime and let things takes care of itself
The future of Bitcoin is what we don't know but we can't take the part of endorsing Bitcoin if it won't yield better things in the future. Bitcoin is understood for its longevity to administer profits, the more investors trooping into Bitcoin, the more years it lasts. I feel that Bitcoin won't die until the last mining is done, year 2140 till the last block is mined, consider our investments in safe hands. In a short time from now, Bitcoin will be competing with Gold in terms of market cap, as long as Gold remains am confident that nothing less than 100+ years Bitcoin will remain as well.
