Why are profits so low?

[X-ray]

With a lot of people are mining and the difficulty rises and the electricity plus the hardware this are the things to consider why the profit is so low 

Even big miners are putting more and more new rigs everyday while at the same time a small miners can do nothing to compete with it. But it's about there was a problem when OP was decreasing a lot on its profit from his mining rig. Those factors should be the main factor.

Considering the price of Bitcoin and Altcoin has a downtrend certainly affects the profit you get. But we can see that the price of Bitcoin is starting to stabilize and move up. hopefully, it will be a good income for miners.

The price of ETH and mining are not always corrolated together.

Reason being that even if the price of ETH rises, so will the difficulty because people with expensive power will re-power up their rigs.

The reason why mining was profitable again in 2016 was because nobody was mining. People sold off their rigs in 2014-2015 and forgot about mining in general. The price of ETH back then was low, but it was much more profitable because there was less competition.

Right now the competition in mining is enourmous.

yes same opinion. The competition in mining is really strong and the small miners don't have a chance to profit much now.
The only way to get more profitable is to mine and keep the coins, until the price goes up again.

I think that the profit is low because the market is no longer growing fast. In order to get a good profit from mining, it is necessary that the coin that you mine grows greatly in price.
