Was about to jump into this coin but from what I can tell... This coin is dead.
the main website does not load (
http://www.highvoltagecoin.tech/ ) and it even says this...
Buy this domain
The owner of highvoltagecoin.tech is offering it for sale for an asking price of 3500 EUR!
So I would recommend waiting for the developer(s) to get active again before investing any large amounts.
