Quick comparison Riot v Taal
First no comparison on the business model, Taal is the outright winner here. They understand as transaction processors, we need to work with the businesses, its about transactions, not blocks. Most miners will have no future once the block rewards disappear. ( Riot probably one of them )
What Riot does have is processing power, with more coming online towards the end of year. Currently around 2500PH rising to 4000PH.
TAAL is about a 10% of that. With 270PH rising to 400 PH later in the year
Riot is valued at 3.6 billion.
Taal just 110 million
An easy triple for TAAL based on nothing more than pure computing power, never mind looking at the superior business model.
