Here is something I just realized today and I believe there is a lot of users who never thought about it.
As the title says:
Cryptocurrency Market Capitalizations are misleading When you look at the chart of Total Crypto Market Capitalization like this one on
coinmarketcap, casual observer is probably thinking that we have lost more than 500B dollars of investment in cryptocurrency in one month. From almost 800B market cap has fallen to almost 250B in one moment (now we are back to almost 500B which looks much nicer).
However this is nowhere near the truth.
As most of you probably know
Market cap = price x total coins in circulation which sounds ok until you give some thought to price and total coins factor. You don't know how much of total coins are available for trading and how much is in long-term storage or lost.
The market cap of the coin doesn't tell you how much money is entering or leaving that market.
I don't know how to actually explain the problem so i will try with the example.
Lets say I have a total supply of the coin: 1.000 coins
I sell to my friend 1 coin for 10$
Market cap is now: 10$ x 1.000 = 10.000 $
My friend sells that same coin to his friend for 2$
Market cap is now: 2$ x 1.000 = 2.000$
So you could come to conclusion that my project lost 8.000$ dollars while in fact only few dollars changed hands and only 1 coin has been sold. 999 coins stayed in long-term storage. This is of course highly unrealistic example but I hope you get the point.
It is really difficult to get to correct numbers for the amount of dollars that crypto investments lost during this crisis, but most people/articles seems to agree it should be in the range of 50B dollars. Nowhere near 500B as the market cap would lead you to believe. Same goes for the bull runs as well. When you take above into consideration then the whole thing with volatility in the market is much easier explained.
I hope I have given you something to think about. If this is mentioned in some other topic please put the link in the reply because I haven't stumbled on the matter trough my browsing of the forums.
That is the basic way to calculate market cap of any investment or trading asset. Same is true for real-world stocks or bonds as well. While the total circulation of coin will always be factored in, the price depends on the exchanges. I believe coinmarketcap uses average method while calculating the value or market cap of a particular coin and it is the best method to use. Let me try to explain it below,
For bitcoin, let us assume that the coin is trading at below prices in various exchanges,
Exchange A: $10,000
Exchange B: $9,998
Exchange C: $10,005
Exchange D: $9,990
So, the price of the coin will be calculated as per the average value which is, ($10,000 + $9,998 + $10,005 + $9,990)/4 = $9,998.25 (market value of bitcoin)
The second part is the number of coins in existence. Since it is impossible to know how much coins are in cold storage or how much is burned out. The best approach is to factor in all coins in existence. Lets assume, we have 3,000 bitcoins in existence. So the as per the above scenario, the market cap of bitcoin will be,
$9,998.25 X 3000 = $29,994,750
I am sure there are flaws in the market cap calculation, but this is the best approach that is adopted by the industry. We can't say it is misleading because it gives you an idea of the overall market.
Coinmarketcap excluded all South Korean exchanges from their calculations in recent past because the value of bitcoin was significantly higher. When bitcoin was traded at $10k, the South Korean exchanges were trading it at $15k, which was actually misleading. But after the exclusion of those exchanges, the current market cap and price is somewhat near to the reality.
