With currently ~ 204060373384 coins in existence and a price of 5 sat per KARM we have a
Market cap of 7.274.752 $, which would be place 15 at coinmarketcap. I think this is way too overpriced and KARM will see a LTC market soon. Even buying at 2-4 sat is very risky imho.
See the marketcap here (

Its close to only 217,000 USD.
Your calculations are wrong.
