Regulating the digital currency to its core would not be the best option. What i meant here is that regulating how its formed, how much needs to be made, in what order, and location specific and the pricing. Not everything needs to be controlled and checked. What certainly can be tweeked in tge existantial system is thw way to track a transaction, may be only if needes though.

How transactions are irrevocable sometimes turn out to be an issue. And it identity which is kept secret is a good thing in security terms but when need arises, as it may in case of crime, extortiom and laundering cases, it is what stops the investigation to proceed. So some tweeking here and there needs to be done. Only if developers could do it remotely in the existing ceypto i.e. bitcoin, and not create some new crypto every day.
