There is a lot of "baked air" in there. Especially with coins that don't have a fiat pairing. Coins that can be bought only by crypto share their value with those other cryptos. They don't add up, like CMC wants you to believe. That's a big major flaw of CMC.
Example, simplified, You buy a BTC for 1 euro (BTC value 1 euro), now you use this BTC to buy one CoinX. CMC will both give 1 euro as value (total market cap is 2), while only 1 euro was actually spend.
In addition, we have also all ICO's where someone puts 10,000,000 flapdrol-coins on the market and a friend buys one Flapdrol for 10 euros and, hoppa, Flapdrol is worth 100 million on CMC.
according CMC all crypto's have a Market Cap about 375 billion euro. I think there is only 0,1% - 1% Fiat invested in crypto to produce that 375 billion CMC , the rest is baked air.
