First and foremost, you will need to create a cryptocurrency wallet to receive Bitcoin. There are many types of cryptocurrency wallets, but most likely, you will need a hot non-custodial cryptocurrency wallet with a constant connection to the blockchain. You can create a cryptocurrency wallet using CoinsPaid
or choose any other solution that you wish.
After creating a wallet, you will receive your Bitcoin public address that you will use to receive funds. Cryptocurrency keys come in pairs: private and public. Private keys give you access to the coins stored on the blockchain and should be kept secret, while a public address can be shared with anyone for people to send you BTC.
