It possible to create some smart contract earning ethers? In general it should be like investor sends eth and receives tokens that can to exchange or sell back at a profit. This is profit shouldnt be based on trading or holding.

When you say "earn", do you mean increase in value?

Are you asking if you can create value in Ethereum just using smart contracts? 

No.

I mean create contract with logic that for seller this token will be have price 1*X eth, X > 1, and for buyer it will be 1 eth

Yes, that is possible.   But you would need to create the token; how would you do that?

It is possible to write an ERC20 token using Solidity

It is very possible to create smart contract for us to earn ETH as long as you have your own utility token under
by ERC20, because without this utility token there is no chances for you to earn Ethereum, just simple as that dude.
But you can still make your own research regarding about this thing, Good day ;)

maybe someone has an idea how this should work, some kind of algorithm or logic?

The smart contract is easy - it's putting the value into the token that is the hard part.

I assume you'll want a cut of maybe 10-50%?   What are you bringing to this project?

If I will put making money as a value into the token?

Smart Contracts can be programmed to do almost anything. The ICOs were based on this simple exchange where you sent Eth and got back the ERC-20 token. When you say that the the smart contract should "earn" Ether, it essentially means that somebody putting ETH into the contract should get some ETH back when the token price increases.

That is the basic concept of several staking and yield farming projects which made a lot of rich people a lot of money in the past days. For this, you need the ERC-20 token to have some value. Unfortunately, there is no value to be found behind MOST of these projects. Affiliate marketing cannot be the answer instead of a long-lasting project that accrues value due to an actual use case. This is basically the holy grail of Smart contracts or DeFi.

From your logic and it seems like you wanna create a garbage token that will give advantage to the developers to farm the money and the buyers were being scammed caused by the price will be going down into the 1 ethereum. lol

Why don't 1*x for seller = 1*x for buyer? If you are wanna taking profit from selling your token and buyers will be loosing the value from your token and you're the same like scamming others.

No, developers should get money only from fee.
In my idea, the seller is not the owner of the contract. I mean the seller is the owner of the tokens who buyed and wants to sell them.

The logic is:
  1. Person A buys 1 token for 1 ETH.
  2. Person B want to buy 1 token for 1 ETH in the Person A.
  3. Person B will spend 1 ETH and will get 1 token
  4. Person A will get 1*X, X>1 ETH

Then Person A made a profit in X ETH, and Person B can make a profit when he will sell tokens

It looks interesting, but how can seller sell 1 token and get 1*x eth if buyer pay only 1 eth?

Its not possible to do that, furthermore if "fee" means gas fee, then its goes to miner not to the developers of ethereum or smart contract. But maybe you can make an decentralized exchange smart contract which take somes fee from the users and send it to your wallet, but i dont know someone will interested in kind of that exchange unless you provide some benefits.

I have an idea how to make it possible to earn Ether using smart contract.

Imagine a company that buys raw materials, produces some kind of goods from it and sells with extra charge. Then another company buys this product as a raw material, also produces the goods, also makes an extra charge and sells it to another company. And so on by chain, as it works in the real world.
The goal of the company will only in order to sell its own product to another company. And this another company needs to buy raw materials to produce goods, sell it and earn.

If you simplify this logic and convert it to the financial instrument, it can be implemented using a smart contract.

We are calling it wrapped ethereum. AAVE has did this, they have their own ethereum which pegged to real eth 1:1. We also have wrapped ethereum on binance smart chain ( binance ethereum ). It is not only use for TS says. It is used for trading on smart contract or smart contract for lending.

I know what you mean, person A will get 1 ETH back, plus X ETH as the profit, right ?
You can't create the X ETH from nowhere. Maybe you can change X ETH with X other token.
So, person A will get their 1 ETH + x amount of other token when the main token sold to person B, so the profit is in other token.

But with this concept of the project you explained, somebody can make multiple addresses and they just buying token between their own addresses to
get more profit, that is the loophole and you must find a way to prevent that.
