I agree with these thoughts. First of all, because the number of users will create additional competition for a common pool. This means that the authors will become more difficult to earn STEEM in the future. In addition, the complexity of mining is also increasing. The more the price of one STEEM will be, the less the payments (payments in STEEM) will be received by the authors.
In my opinion, we are in that period of time when we have many opportunities.
