It is always hard to calculate the real market value. Because the market or particular company's value is determined "on the last price, which was paid for the asset".
For example if Company A, has 1 mln coins, released in ICO and the price for a coin was 2 usd, so the market value of Company A, is 2 mln USD.
Meanwhile company B, has 1 mln coins, but 80% of the coins are locked, and held by the management team, so only 200k coins are in the markets, and open for purchases. Then on some exchange coins are being sold for 10 USD per coin, of Company B. That gives 10 x 1 mln = 10 mln market valuation for that Company B. Even if the max coins to purchase is only 200k, which would cost total 2 mln usd, but the market VALUE IS 10 mln USD.
You must be getting me by now :)
nice feedback, ok thanks I'll try
