look at market cap
Market cap has ZERO direct effect on mining profitability.
PRICE does, but price is only one of the components of market cap.
Keep in mind that the coin with the SECOND highest number of GPUs pointed at it is probably ZEC (at ballpark 1/2 to 1/3d as many cards as ETH has) yet it's only #17 on your market cap list.
How long a coin has been around has a major effect on market cap, as a coin that has been around a long time like ETH will have a lot more coins in existance vs one that is less than a year old like ZEC.
I don't see ANY chance of a lawsuit over "lost mining potential" due to poor drivers getting traction against AMD or NVidia - they do NOT make their cards for mining, they make NO guarentee of their cards for mining, etc - the only possible tort would be for "breach of contract" and there IS NO SUCH CONTRACT for them to breach.
Might have a faint prayer vs the AFTERMARKET makers that are making "mining cards" but I doubt even THAT would get anywhere in a court.
