I agree that blockchain is not necessary in all the situations. Some scenarios are better of solved without using blockchain.
But I guess people wanted to use the hype word in order to make money and so it happened.
I have read a theory where they have explained that any technology or so has a timeframe where it is extremely hyped and is booming in the market after which it drops hard. It is after the drop, that the real rise begins and derives the actual use of the technology.
So, may be 2017 was the hype period of blockchain and after that it dropped. May be it will now show us the actual growth and use of blockchain.
The hype was all about making money than anything else. So many companies and startups came into inception since 2017 with the goal of profiting from Blockchain's success. Yet, we've seen how most companies have failed while others have reduced their employees in order to minimize losses from the long-lasting bear market which began in 2018. Now that Bitcoin and other cryptocurrencies are constantly declining in price, everything has gone silent. There isn't the same excitement there was back in 2017. I guess that crypto and Blockchain tech has reached a timeframe where the world expects results instead of false promises delivered by hype.
Once crypto does its thing to deliver real use cases for the mainstream world, then I believe that prices will start to rise across the market. While this may not be comparable to the events of 2017 (where everyone was full of hype), the industry will grow positively over time as investors continue to support Blockchains that are truly useful to the world. The reason why most people have declared Bitcoin and other cryptocurrencies to be "dead", is because their prices have declined considerably across the crypto market. Believe me, that once prices start to rise, you can expect people to revive the "hype" once more.
Nonetheless, it's not about the price but rather crypto's core Blockchain technology. As long as the same is able to provide financial freedom, people will have a choice against the traditional economic system of today. If they focus on the money instead of what really matters, then I'm afraid the industry won't be going further in the future. Just my thoughts
