Sorry to disappoint you but this does not work well. I think as coins will increase in value depending on their acceptance and trust.
If your chart is true, tell me why Catcoin not worth the same as 1 Bitcoin
You're right, the market cap depends on acceptance and that's why catcoin doesn't worth 1 BTC. Many coins with similar background and vastly different supply have almost the same market cap though, and price per coin magically settles according to coin number. I believe that coin price is mainly the function of the adoption level and mining profitability. But there're two extremes:
1.
Very big number of coins. I'm talking few billions or higher. This is ultimately reflected in low price per coin, but it's easier to reach very high market cap. Reason one is trading against BTC, when 1 satoshi increment represents a huge % change – coin is easier to pump. Reason two is that it seems to be easier for market to accept a high cap with low price per coin and huge number of coins than something in the middle (close to bitcoin proportions). However, there've been too many scamcoins/jokecoins/clones with billions/trillions and everyone is tired of those.
2.
Very small number of coins. I can only think about RPC, 42 and BitBar. Trading against high BTC price per coin can bring attention on an exchange and the coin will stand apart. I believe that with proper promotion this approach could be very successful! And it's relatively new to the market (most new coins are from the first group)
