Re: What is the Best consensus in your opinion? POW, DPOW or POS?
POS is the best consensus mechanism, we know that in this time global warming has become the real problem an with the POS system and it will be more suitable because we will not waste our energy to secure the decentralization of blockchain. It's conservative. Have you seen how much energy that has already consumed to secure the blockchain? 
I totally agree with you.
Some people said POS is for wealthy people. But I disagree with them that, because:
To mine (POW) => we need Money to buy Mining machines (ASIC, GPU...)
To stake (POS) => we need Money to buy Coins, send it to a wallet to start staking.
