RT38 - Some thoughts of a compliance officer on crypto-currencies

When hearing for the first time about the blockchain technology and the creation of cryptocurrencies several years ago, I was quite attracted by the concept. As a compliance officer, I saw the block-chain as a way to increase the traceability of the cryptoassets. As from the original mining process up to the actual holder, everything is traced in a way that cannot be contested, hacked for, nor destroyed, at least for the time being. Moreover, traceability files are supposed to be accessible worldwide in an easy way. What could a Compliance Officer object to this?
