Hello, I think to get started you need to have an account first, you can register with a trusted platform or website, such as Binance or Bittrex. I suggest to use a demo account first before directly depositing your money, you can
practice first to hone your skills in making real trades using a demo account.

Don't forget to always monitor the price of the currency you are buying on the marketplace, if you have started your trading business. In order to protect your cryptocurrency, you must have a wallet. The wallet saves your private key and public address which helps you store, send, and receive cryptocurrencies.

Don't rush into making decisions when trading. Especially in buying and selling currencies. because it will be risky if we do it carelessly.

Keep the spirit. I'm sure you can, if you want to keep trying and learning.
