I think node is little to late. Other big smartphone companies have their own system for wireless charging for a couple of years now (and cheaper than node's)
What is Your advantages?
Sorry mate but can you name 1 smart phone company with the same tech.
Big smartphone companies are yet to make it to blockchain and this is why I believe Node will be the first to implement it.The buyback system will also reduce the supply over a period of time.So my question here is what is the periodic buyback time and tokens being burned?
