How to start cryptocurrency development from scratch?

Starting cryptocurrency development involves several critical steps. First, define the purpose of your cryptocurrency, including whether it’s for financial transactions, smart contracts, or a decentralized app. You'll need to choose a consensus algorithm, like Proof of Work (PoW) or Proof of Stake (PoS). Once decided, you can fork an existing blockchain (such as Bitcoin or Ethereum) or build a new one using programming languages like C++ or Solidity. After developing the blockchain, ensure it has an efficient transaction mechanism and is secure. Testing the currency is essential before launching. Post-launch, you’ll need to promote it, list it on exchanges, and establish wallet compatibility.
