> If you have the impression that serious cryptographers are knee deep in the problem space of trying to make sure cryptocurrencies are actually secure, revise your expectations.

I'd say the teams behind Bitcoin core, Ethereum and especially Zcash can hold their weight to a certain extent.

It's still very early days though and there is a lot more serious research that needs to be done.

I'm not saying that they are perfect, some of those teams have made mistakes, but it's still a cutting edge field so it will take time for more experts to get involved.
