It's similar to the situation with credit cards. There is a whole industry related to working around the problem of constantly disclosing the secrets, such as refunding stolen funds. Likewise we have had to rely on banks to control digital money since we did not have a good alternative. And now there are many regulations and compliance officers etc. dedicated to preventing people from cheating, stealing, or irresponsibly using customer funds. But at the core level the problem is that these the bank ledgers are secret, difficult to verify or connect together for tracing purposes. Cryptocurrency means using math and computer science to solve these types of problems in a holistic way. Like everything else, people have abused this technology (such as using it to sell services that are antithetical to the core concept). But that doesn't mean they aren't important advances.
