Probably I wasn't precise enough in explaining why I made this suggestion. When we are talking about privacy/security focused coins, its de-/centralization becomes an integral part of it. When I think about security I also assume the safety of my funds in the broad sense. I personally don't believe in coins that can't be mined, since it breaks the equality principle, up for me it means centralization, concentration in hands of specific group of people, issuers of that coin. IMO non-minable coins are closer to the dollar and FRS, rather than to bitcoin and crypto in general. May be it's only I who see things this way.

Probably I'm overestimating the importance of this aspect and you don't feel like adding an extra column just for that. But what if we expand it to the general column about Mining? There we can mention whenever the coin is minable, ASIC-resistant, botnet resistant, etc (or simply mention the current mining algo if any).
For example, ZCoin developers are working hard on their MTP-algo that is purposefully memory intensive making XZC ASIC/Botnet resistant.

SafeCoins, I'm interested to hear your opinion on that.
