Which are currently the most famous
DeFi projects?

Chainlink (LINK) is a cryptocurrency project with a vision to foster a global, decentralized network of oracles across countless computers that will provide reliable real-world data for smart contracts running on top of various blockchains. Chainlink takes the performance of smart contracts to the next level by providing access to real-world data, events, payments and more without sacrificing the security and reliability inherent in blockchain technology.

Fantom is a BlockChain that supports smart contracts and is powered by its native token FTM. After raising $40 million, Fantom launched its mainnet in December 2019. Its Blockchain is fast and affordable. In 2021, however, it also proved that it can support its own decentralized finance industry (DeFi).

Polygon is a cryptocurrency with the symbol MATIC and also a technology platform that enables the connection and scale of Blockchain networks. Many crypto experts believe that Polygon (MATIC) can be a great choice for your investment portfolio with the potential for its price to rise significantly.

Algorand is the most decentralized, scalable and secure Blockchain infrastructure in the world. From decentralized finance to NFT generative art (and everything in between), their sustainable Blockchain powers the economy models of the future.

Types of NFTs

NFT probably has the biggest impact on the art industry. Art and works of art are now traded on NFT platforms, and creators and artists are making enormous sums by auctioning off their art in the form of an NFT. Most digital artworks are stored on separate web servers, while physical masterpieces are stored in art galleries, art clubs, and similar.

Real-world objects such as land and real estate are another infamous sensation in the NFT market. For example, home owners can sell a portion of their property to investors through the issuance of tokens as fractional ownership. This gives investors certain benefits such as income sharing, priority access and reduced property occupancy rates.

Photos can now be tokenized thanks to NFTs. If you are a photographer, you can sell the ownership rights of your images by issuing a certificate. You can also attach a royalty agreement to your NFTs, which entitles you to a percentage of the profits made every time your NFTs are sold to someone else.

Video NFTs are just as artistic and collectible as photographs. Video creators can now sell 10-second clips for as much as $6.6 million. Recently, TikTok entered the world of NFTs by releasing its collection of digital assets inspired by trending videos.

GIFs have been around for a while, but now they’ve made their way into the realm of NFTs. These animated images can now be authenticated and then exchanged and monetized. Last March, a link to a GIF was sold for $25,000 in an Ethereum auction within 24 hours of the GIF being put on the blockchain.

On NFT platforms, artists can publish their new music on the blockchain, allowing fans to instantly access and purchase the material.

Some platforms offer the option of embedding a royalty share, which allows fans to earn money from the music they love by simply promoting it on social media. It’s a pretty new and exciting way for musicians and their fans to connect and interact.

Passive income
using decentralized finance

Here is an example of a staking option on the Binance exchange:

For comparison, we can look at how you would go about staking the HEX coin by interacting directly with the protocol and not through an intermediary such as Binance.

First, we need to create a Metamask wallet, which we install in the Google Chrome browser. We transfer the amount of HEX coins that we intend to pledge to our wallet and then connect to the website with the wallet.

Here it will be necessary to give the website access to our wallet for interaction, with the HEX protocol.

Once your MetaMask wallet is connected, the page will automatically update (as shown below). Then click on the “Stake” tab.

Here you will be able to create your position and choose the length of time and amount of HEX coins you intend to stake. It is also possible to create several different positions, i.e. for different lengths of time.

Once you have selected the desired amount and length of time, the Metamask wallet will again ask you for permission to continue. Once the transaction is confirmed, you will notice that your newly created stake is displayed under the “Active stakes” column and will be on the waiting list until the day turns ends at 00:00:00 UTC (when all stakes are updated).

In principle, the process is the same for all projects that offer the possibility of staking, so the steps will be quite similar regardless of which cryptocurrency you want to stake.

First of all, it is important to know that you can add any token, that is built on the Ethereum network and isadded in combination with the same value in Ethereum token, to liquidity pools. So you need:

  • A Metamask wallet
  • Any ERC-20 coin + ETH tokens
  • Uniswap

In this example, we will use the Uniswap platform and add DAI cryptocurrency to the liquidity pair. The process is the same for all ERC-20 tokens.

To get started, you will need ETH and your target ERC20 token (DAI) in the same wallet.

Once you have your tokens, click on the “Pool” tab and make sure the “Add liquidity” option is selected at the top of the page. You will see ETH automatically selected in the top box and select your token in the bottom box. You may need to click “import” next to the token and approve the contract interaction notification in your Metamask wallet.


Select the amount of tokens you want to add and the corresponding amount of ETH will be automatically filled in the box above. At the bottom you can see the current exchange rate and pool size. Click “Add liquidity” and approve the transaction notification through the wallet.


Once the transaction is confirmed on the blockchain, you will see the amount of ETH and DAI liquidity provided and your share of the pool in percentage. This liquidity is used when users trade ETH/DAI on Uniswap, meaning that the ratio between your ETH and DAI may change over time. You may have more ETH or DAI depending on how people trade, but the dollar value will remain the same.

To remove liquidity and receive your rewards, make sure you are back on the “Pool” tab and select “Remove liquidity” from the dropdown menu. Select the ERC-20 token you have secured liquidity for and the balance shown above will equal your number of LP tokens. Click this number to fill the field with the total pool share.

Once the transaction is confirmed on the blockchain, you will receive ETH and DAI to your wallet, the LP tokens will disappear and your pool share will return to 0.

Dangers and mistakes that you can make on crypto exchanges

Too high fee when transferring cryptocurrency.

I am attaching an example where a transfer from the exchange to the Binance exchange was carried out. Since in this case the exchange had a high fee for the ShibaInu cryptocurrency, it charged as much as 5M commissions for the transfer of 11M crypto-currencies.


Let’s look at the example of network selection when transferring Ethereum cryptocurrency from the Binance exchange to the exchange.

When we select the option to transfer cryptocurrency on the exchange, it gives us a choice of different networks. For the Ethereum cryptocurrency, we will choose the Ethereum ERC20 network. It is important that the same network is selected on the Binance exchange. In this case, it is the ERC20 network.


Despite the fact that the BSC network has a lower fee than ERC20, it should not be chosen. For example, if you chose the BSC network on the Binance exchange and have been approved the transfer, those funds would be lost. You would only use the BSC network if you were transferring from one Binance user account to another Binance user account. This network was created for this purpose, as it allows the lowest transfer fees within the Binance exchange.

How to set gass fee for transactions in the MetaMask wallet?

Gas fee can be set and selected in the MetaMask wallet right when you start the transaction. You can login to your MetaMask wallet and go to the “Send” section. Here you will need to enter the recipient’s wallet address and the amount.

Below these two boxes, you will see three different buttons to choose from. With these buttons, you will be able to see the gass fee you have to pay to complete the transaction at the “fastest”, “fast” or “slow” speed.

As you can already guess, you will have to pay a higher gass fee to complete the transaction as quickly as possible.

You don’t always have to rely on MetaMask’s suggested prices. It is possible to follow the steps above to determine your gass fee rates. In this way, you can significantly reduce the transfer fee in your Metamask wallet.

Stop-limit function

You have 3 trading options available in the trading platform under the spot tab:

We need to enter three parameters: the stop price, the limit price and the amount of tokens we want to sell:

We enter the price at which we want our limit order to appear in the order book.

We enter the price at which we actually want to sell our token.

In the amount field, we simply enter how many tokens we want to sell.


Prior knowledge of computer use or age is not important. With the manual, we have successfully helped both younger adults and those over 70 years old. Buy low, sell high. Now is one of the best moments in the last year.
