Market Cap size
XRP has a market cap of $32.8 billion at the time of writing (XRP price at 0.61 USD). The fully diluted market cap of XRP is closer to $61 billion. The total value of all cryptocurrencies combined is $1.38 trillion, so XRP has a share of 2.3% against the total crypto market cap. The estimated value of all silver in existence is around $600 billion (silver price at 23 USD/oz). This is based on the total silver mined, to date, which is some 1.4 billion kg of silver, taking into account that silver corrodes and just under half of that silver no longer exists as a metal.
