However, it's important to note that Ethereum has its disadvantages. While the blockchain is applauded for its security and verification protocols, it's having trouble with scaling. As such, the Ethereum blockchain is often slow with processing transactions. Another downside is its expensive fees known as gas. There are other competing blockchains that aim to take Ethereum's crown (e.g. Solana). The final fee to pay attention to is withdrawal fees. These vary from platform to platform and crypto to crypto. Some see this site exchanges give a certain number of free withdrawals each month. Most platforms list their fees for each cryptocurrency and they can vary from a fraction of a cent to $100 or more. It's sometimes worth converting your assets into a cheaper crypto before you make a withdrawal.
