Blockchain technology generally is the right solution for the future, but crypto which is the product born out of it is not actually the main solution, there are projects that could use blockchain technology as solution and may not have to establish cryptocurrency, it is when we deal with financial system  of the world that cryptocurrency probably comes in  which bitcoin as the main coin should have been enough solve resolve that angle if not for its scalability issue and speed, which is why we have few other cryptocurrency to come and resolve it and serve as an alternative, but the crypto market has been turned to something else now, they mainly use it for just assets alone which is why people just rely on it for investment rather than its utility, thereby causing all those complains because many of them are not able to meet up to the high expectation of investors.
