Blockchain will be passe' the same day as the sun rises in the west. DPW needs to play its strongest cards: its position of leadership in the power supply niche.
The world is going to have crypto currencies involved in the international economy in almost no time. That bright light in the tunnel up ahead of us is not the light of normalacy shining at the tunnel's exit.... it's a change-agent freight train called "The Blockchain" heading our way at the financial speed of light itself.
Good luck to you, my man.
To think that blockchain is not massively important is a very bad investing mistake, IMHO.
