Beyond watching the charts, you should also understand the basics: smart contracts
A smart contract is a set of code deployed on a blockchain. When preset conditions are met, nodes across the network execute it automatically according to the code.
Smart contracts cannot access off-chain data on their own. For external information such as exchange rates, they need an oracle.
Deploying a smart contract on Ethereum requires $ETH to pay for Gas. Current price: 2414.81.
Compare information from multiple sources before making a decision; don't rely on just one source.
