I would argue that the premise of Bitcoin and to a degree crypto at large is that these sort of guarantees will not exist. This movement is very much taking power/responsibility away from centralized entities and putting it back in the hands of individuals. This has a ton of benefits, but obviously there are downsides. Big brother guaranteeing you get your money back isn't something I see lasting into the future.
As a result of the above I think you'll increasingly see individuals and corporations move away from the trusted third part model for data. If my third party vendor (Coinbase in this case, but also
ActiveCampaign and
Hubspot from just this week) is compromised and leaks my user data... as a company I am going to be held responsible by the customer. Expect to see a big transition toward more in-house services from these companies as user data continues to get hacked. The cost of spinning up these services internally is going to be lower than the cost of losing large chunk of your userbase because you're viewed as having security issues.
Wait until hackers, or those they sell the data to, start breaking into people's homes because they know how much crypto they hold. Trusted third party model will not survive, so it is going to be worth learning how to secure this stuff yourself in a private way.
