My credit card doesn't charge fees for international payments, but of course it charges the receiver, and makes a small turn on the exchange rate, but this seems to be slightly lower than a normal bank exchange charge.

In my country, Bitcoin only works as a digital asset, still cannot be used as a digital currency since it violates the laws. So, I think Bitcoin may work vary among the countries in the world. In some countries, Bitcoin can work as a payment tool and everyone can buy the kinds of stuff with Bitcoin. However, Bitcoin is a crypto coin that is already used by many people around the world for various purposes. We all can take advantage of Bitcoin because it has value, at least as an asset.

Each Bitcoin is basically a computer file which is stored in a 'digital wallet' app on a smartphone or computer. People can send Bitcoins (or part of one) to your digital wallet, and you can send Bitcoins to other people. ... You can buy Bitcoins using 'real' money. You can sell things and let people pay you with Bitcoins.Yes you are right and you can buy Bitcoins using 'real' money and you can sell things and let people pay you with Bitcoins. It is a digital currency and not controlled by any government or central government it is . 🙏

how does bitcoin work,??how bitcoin works via (blockchain) is a public transaction record on which the Bitcoin network rests. All confirmed transactions are stored in the blockchain. Thus, Bitcoin wallets can calculate the remaining spendable money and new transactions can be verified to ensure that they are indeed owned by the user. The integrity and chronological order of the block-chain is implemented using cryptography.

Bitcoin is based on the  blockchain.
Many people equate the meaning of blockchain with bitcoin. If bitcoin is just one of the uses of blockchain, and blockchain as a whole is a public information distribution office that anyone connected to can be informed that I think this is one of its greatest miracles and I call it the miracle of transparency.

The practice of digitally adding transaction records to the blockchain, which is a publicly distributed database that holds the history of every bitcoin transaction, is known as bitcoin mining.
Mining is a data-keeping activity that requires a lot of processing power. To guarantee the payment network is trustworthy and secure, each Bitcoin miner across the globe contributes to a decentralized peer-to-peer network.

Bitcoin mining machines perform complicated mathematical problems in order to safely contribute to the blockchain record. When a solution is discovered, the most recent block of verified transactions is added to the blockchain as the next link.

The miner that solves the challenge is rewarded with a block of Bitcoin as an incentive to mine and contribute to the network.
