Interesting to read your historic path in crypto. And I can reassure you that many of the 'errors' you made are in fact normal ones to make for many newcomers to the space. It all looks a lot more easy than it is to trade! Eventually we learn to simply hodl :)

Smartcash is really interesting because of the great rewards it gives. I am still on the fence if I want one of those nodes - they're not expensive. But I have concerns regarding adoption and innovation.. It is going to be a struggle for the coin to survive for the duration!
