The methodology that we currently use to calculate market capitalization and trade volume is a flawed one, and this underestimates the real net worth of Bitcoin and overestimates the same for most of the altcoins. For example, take the case of Ripple (XRP). Out of a circulating supply of 43 billion tokens, somewhere between 35 billion and 40 billion are being held by the promoters. But the problem here is that most of it is being held in an indirect manner. Chris Larsen alone holds 5.19 billion tokens directly and an undisclosed number indirectly. And more worryingly, some 55 billion tokens are being held in the Ripple Lockdown Fund. If all these coins are released as free-float, then the XRP exchange rates would collapse to a fraction of the current levels. But still, while calculating the market cap, all the 43 billion tokens are considered.
The following mining process is being done through the Lockdown and release of funds into the market at certain time period. If the entire volume gets released to the market the value will collapse. Just think the present scenario with the entire volume into circulation. The value will fall off.
