Yes, he is right! Coin CRUX does not provide for classic mining, only masternodes and staking from the crypto wallet.
This is a good choice for investors who do not have computing capacity. POW mining is not for every person. But almost everyone wants to make money on cryptocurrencies. Taking into account that, no more than 10% of people on earth know about cryptocurrencies.
It seems to me that 10% is a very optimistic figure. I read statistics on the Internet that less than 1% of all inhabitants of our planet deal with cryptocurrencies.
