Another interesting point. To manage this two-tier blockchain, you only need one account. It's good that at least there are no difficulties.
Many will disagree, but I have found a Golden niche. I will be happy to add the VestChain project to my list. I have been involved in many ICO such as : OPP Open Wi-Fi, Inlock, POMZ and Endi. I am responsible for the choice of the company And I'm sure at least one of them will make me rich.
