At the same time, 100 years later, I believe that Bitcointalk will always exist with Bitcoin. 100 years later, there will still be Bitcoin supporters coming here, posting and communicating.
In the next 100 years, Bitcoin will be increasingly popular and more and more used by many agencies and countries. And Bitcointalk will be a legendary forum that discusses Bitcoin and Cryptocurrencies, And our children and grandchildren will see the posts we make now.
And they will also continue to discuss Bitcoin, and maybe at that time a new technology will emerge in this Crypto whose technology has a high advantage over the existing Crypto.
