Bitcoins seems to get less worth. Is it because the mining software are getting better and better?

What do you think about bitcoins future? Will it still exist within 20 years? 20? 5? 2?

I hope BTC will survive  'til its maxed out limit,  but as always its depending on us.. we need to evolve too..
Do not ask what bitcoin could offer for you, ask what you can do to make it last. More legal ways to use it instead
of "SR" style places.. and we're good to go.. price will vary and there will be better ways to mine.. also we have
competitive coinchains to mess things.. but after all i think its only needing some stable users who dont just mine and dump..

I believe bitcoin rellated software are getting better today but they still needs to be easier to non techs.

It is very hard to say something about the next 20 years.

Life cycle in real world.
Engineers try to make better and better equipment to facilitate people's everyday life. At the same time, however, world creates shitload of "even more stupid" people. Until end of human race this treadmill does not stop turning.
