The Dotcom bubble in 1990s can be a good thing to learn from. After the bubble, about 10 years later, in 2000s Internet began to massively invaded into our lives and since 2010s, it impressively changed the world. It means 20 years at least to change the world.
How about blockchain technology? I think next 10 years or 12 years, we will have a very different world, with massively revolution from blockchain technology. It will be something partially related to bitcoin halving scheduled years but not strongly correlated like that. After the latest halving (in May) Bitcon's jumped into its deflation phase.
