https://coinmarketcap.com/charts/
Global charts, scrolling down to "Percentage of Total Market Capitalization (Dominance)", selecting only "Others" altcoins.

I can see that there was a turnover at March 18 2018 and since then the percentage of the marketcap is steadily rising. From 17.0 % on March 18 2018 up to 20.8 % today April 3 2018. Smaller altcoins seems to gain in popularity lately.

I wonder what are your conclusions of this?

I want to make a list of the available calculators for Mining profit.

Do You know more calculators Worth adding to the list?

I wonder if there is any coin that require both good CPU and good GPU for mining?
I know there are algos that work on both CPU and GPU like cryptonight.
But I wonder if there is any algo thet is bad on CPU, bad on GPU but good on CPU and GPU combined?

I am thinking CPU only coins get abused by botnets.
GPU only coins get abused by peple wigh big multi-GPU mining rigs.
But a combined algo would be good for gaming computers with a good CPU and a good GPU combined.

I don't think it will work on my old HD7950 but still interested to see what improvements you get with your AMD cards on Linux.
