Sam Liban is a self-employed senior consultant with a particular expertise in DLT-systems. In this episode we talk about public blockchains, like the Bitcoin, how central some of the so-called crypto currencies have become and about manipulation within the community. Sam also shares his opinion about enterprise solutions and the currently high transaction costs of Ethereum. Towards the end we talk about the potential development of Altcoins and whether they will remain in the years to come.
