When you have won an allocation in some project, your main task is to get tokens as quickly as possible and merge them into DEX and get the maximum profit. At such moments, the bill goes by seconds, which means you need to reduce the number of seconds spent...
As we know, it is not always possible to do this because of too many people who, like you, want to sell as much as possible. And this situation boils down to the banal "who's the first - that's the slippers". In this article, you will learn how to make sure that the "slippers" are yours with a high degree of probability...
Token pre-approval
Gas for claim token
Slippage
Gas on swap
When you sell a new token on DEX for the first time, you are asked to make an approval of the token. This app allows the smart contract to take tokens from the wallet and change them to others. You can make an approval of the token through the explorers. If you work on the Ethereum network, then you use Etherscan If on BSC, then use BSCScan and so on. A small guide:
Look for the contract of the project token that you are going to merge, usually they are published on off sites and social networks of projects. Let's make an approval of the token using the example of BIFI (0xCa3F508B8e4Dd382eE878A314789373D80A5190A)

Go to BSCScan and insert the contract address into the search

Scroll a little lower and click "Contract" - "Write Contract" and open the walle

Open the "Approve" function In the spender (address) column, you need to insert the address of the DEX smart contract, you can find them in the DEX docks.
For example, pancakeswap V2 has a contract - 0x10ED43C718714eb63d5aA57B78B54704E256024E In the amount (uint256) column, you need to insert the number of tokens that you allow the smart contract to take from the wallet in !Wei format!
1 BIFI = 1'000'000'000'000'000'000 Wei or 1'000'000'000 Gwei
I recommend writing a huge number of nines so as not to catch the transaction limit (fail) at the most important moment

Click "Write" and sign the transaction in MetaMask or another wallet. After the transaction is completed, the token approval will be ready.
Sometimes a project can distribute tokens through airdrop, sometimes through a brand. Branding is when we ourselves take our tokens from the smart contract of the project. That is, in order to receive tokens, we must initiate a token branding transaction. Other wallets should do the same action, i.e. now there is an additional task to overtake a large number of competitors at this stage and win a couple of seconds.
The only way to do this is to increase the minimum level of commission that we are willing to pay so that our transaction is processed by the blockchain faster than the rest.
To do this, 2-3 minutes before the claim, we go to the gas tracker of the blockchain in which you work and look at the current level of the fastest transaction. Gas tracker on Ethereum, gas tracker on BSCScan.

Then, at the time of creating the transaction, click on "Edit"

In the Gas Price (GWEI) column, the amount is 2-3 times more than it was on the gas tracker. We save and confirm the transaction.
Slippage or Slippage is a setting in the DEX interface that sets the % allowable discrepancy between the price at the time of signing the transaction and the price at the time of its completion.
Simply put, if you put a slippage of 5% at a token price of $100, then the transaction will be completed successfully if the price remains in the range of $95- $105. If the price is beyond this range, the transaction will be canceled.
To adjust the slippage, go to the DEX interface and click on the gear and write 8-10% in the Slippage Tolerance column, it is better to put up to 15% on particularly volatile tokens.

Here you need to work as in the second paragraph about the commission on the claim.
But only here you need to analyze a little more data.
If you look at the token price chart and see a very large possible profit in x, i.e. the purchase price differs by 15-30 times, then it is better to make 3-5 times more commission so that our transaction goes faster than the others and you sell tokens with the maximum possible profit.
It is better to lose $100 on commission, but make a transaction quickly and make a profit of $2'000, than to spend $20 on commission, but make a profit of $1'000.
The commission is set up as in the second paragraph: At the time of creating the transaction, click on "Edit"

In the Gas Price (GWEI) column, the amount is 3-5 times more than it was on the gas tracker. We save and confirm the transaction.
Now you know how to quickly sell tokens with IDO with maximum profit.
