That voting thing was IMHO a mistake.
You'll get those coins which have the most fanatic fan base. But an active fan base says nothing about general trading interest for a dedicated coin.
The most fanatic fan base cannot be a substitute for general public interest in trading in a coin.
Why not simply including those 4 coins which had the highest trading volume shown at coinmarketcap over 1 month?
Trading volume is best proof for interest in a coin. Voting volume is only proof how good an activation campaign for a coin has been going.
