good question, my data is taken from the coinmarketcap.com, which include Tether, bitshares, binance coins... so we could say that don't leave the crypto sphere, even the coins in wallets are included.

what is not included, but perhaps has not left the crypto sphere is the fiat that resides in the exchanges, for exemple i have some euros sitting in kraken (like a bank) this euros comes from some profits i took in past and are not included in the coinmarketcap but in some way hasnt leave the crypto sphere..."yet" lol
