Those running Bitcoin nodes have a direct and authoritative view of the Bitcoin blockchain, with a local copy of all the transactions, independently validated by their own system. By running a node, you don't have to rely on any third party to validate a transaction. Moreover, by running a Bitcoin node you contribute to the Bitcoin network by making it more robust. Running a node, however, requires a permanently connected system with enough resources to process all bitcoin transactions. Depending on whether you choose to index all transactions and keep a full copy of the blockchain, you may also need a lot of disk space and RAM. As of early 2021, a full-index node needs 2 GB of RAM and a minimum of 360 GB of disk space (see https://www.blockchain.com/charts/blocks-size[]). Bitcoin nodes also transmit and receive bitcoin transactions and blocks, consuming internet bandwidth. If your internet connection is limited, has a low data cap, or is metered (charged by the gigabit), you should probably not run a Bitcoin node on it, or run it in a way that constrains its bandwidth (see <>).
