there are many reasons I have to stay. including because I believe that crypto currencies will continue to grow and have a very good future, including bitcoin with its blockchain technology.
The Blockchain is 10 years old now, and right now the technology is not that being used in other things.
I've heard it once on an interview about the Game Table, a game table with the blockhain technology. That is the last time I've heard an application of the Blockchain Technology. I know that there are a lot of ways it can be used but I don't think some people are having an interest on it. Some are more focused on making their own coin, I think.
