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.
You were right to say that coin mining is not for everyone. For example, I never had a mining farm, but I always loved masternodes. For me it is a good coin. This is the future model of crypto investments. Keep coins and they have increased in number. It's amazing.
