You can buy and sell, farming with coins and tokens of Binance Smart Chain only with Pancakeswap. You can buy and sell tokens using Pancakeswap through different wallets. However, if you want to buy and sell a token Pancakeswap from Ether chain network, but you can not. Because Pancakeswap DEX is only used for Binance smart chains.
However, in order to use Pancakeswap DEX, you need to keep BNB smart chain coins in your wallet. However, the network fee is much less if you buy and sell tokens or coins in Binance smart Chain. So I like binance smart chain network a lot. You can use Trust wallet or Metamask wallet to use Pancakeswap DEX. I use Pancakeswap DEX with Trust wallet. However, to use this DEX, you need to have binance smart chain coins in your wallet, because without those coins you can not buy and sell coins. Because it takes BNB coins to buy coins and BNB coins for network fees. So now I will discuss below how to buy coins.
Dapp's work from the wallet. You will enter the wallet first. After entering the wallet, you will get the Dapp option in any wallet. Dapp option means like a browser. And there you can browse. But the wallet is designed to use the Dapp option DEX. After entering the Dapp option, enter the pancakswap.finance DEX.
Then you have to select smart chain network and connect wallet to DEX.
After connecting to DEX, click on the trade button marked below.
You can buy and sell your token after clicking the trade button. You can select coins there. If you want to buy another coin with BNB, you can do so. If you want to buy BNB with other coins, you can also buy it. As you can see in the picture, I have BNB there, so I will buy another token with BNB.
You will select the token that you will buy with BNB. You will see that there is a currency written in select, click there.
After clicking there, you will get a list of many coins or tokens. But if the token you purchased is not listed there, then you will do something else. You can then see below that the "manage tokens" is written.
And then click manage tokens option. Click on the image and then click on the tokens again.
Then you will paste the tokens smart contract address and the token name will appear there.
And then there you will get the import option. And then the token will be imported by clicking on the import button.
Then decide how many dollars you will buy that token. It will show you how many tokens you will get with how many dollars. So you can, I have $0.00625. I am buying another token with BNB. Set how many dollars you will buy the token with, and then click the swap button.
After clicking on the swap button, you will see such an image.
And there you can see the price of token, fee, amount of token, liquidity. And then you click on confirm swap.
And then you will face such an image.
You can share where you are buying the token with which coin, you can see the name of Dapp, you can to see the network fee, you can see how many dollars it will cost. And then you click on the approve button. After clicking the approve button, you are done and then the token will go to your wallet.
However, the problem of tof tolerance to swap a lot of time. I was not approved due to low tolerance when swapping with this token, and then I'm clicking on setting mark while swapping.
Then the tolerance increases. When you swap with this DEX and if not swap then you will gradually increase the level of tolerance.
I finally it in my purchased token wallet. But before you buy those tokens, add the token contact address and decimal to your wallet. This will allow you to view your purchased tokens as you swap tokens.
