Let's wonder a little. The year is 2057.
(By the way, Chris Pratt is the POTUS, sorry about that)
How do you imagine yourself with your bitcoins? How do you imagine the World you'll live in related to the cryptos?
Blockchain rules the world (from elections to the way your grandchildren interact with friends) and BTC is everywhere? Another crypto that does not even exist yet is now the king and both blockchain and BTC are seen as a museum piece, such as a steam locomotive?
The year of 2057 will be a great year for bitcoin because i think that the countries already adopted bitcoin and a lot of malls and merchants in all around the world is related with bitcoin and they are also accepting payment thru bitcoin. The blockchain is the most main stream technology in 2057 and that is a year that worth to wait.
I do not think that blockchain is strong enough to survive to that point. Modern technology is growing very fast, it definitely needs a stronger technology, the blockchain is showing its weakness at the moment, so I think another technology will replace it. .
