Not _all_ cryptocurrencies, no - it's mostly just the scammy ones of little genuine utility and/or technological merit.

Both Bitcoin and Monero have fair distribution; development of neither is done by for-profit LLCs financially supported by any pre-mine, miner tax, insider investment/ICO, or other fancy scheme paid out by either the underlying monetary system or taxed from the users and/or those securing the network, and while Blockstream Inc. does employ Bitcoin Core developers, Monero development is entirely decentralized without even a foundation to its name.

The vast vast majority of bticoins are in the hands of early adopters. It was effectively a premine.

The original comment purports that ridiculous enrichment schemes are a carpet necessary evil for initial and continued development of cryptocurrencies, which is simply not true - what you're pointing out is a different argument.
