Liquidity and spread
DOT has deep liquidity on the large exchanges, so slippage is small at retail size. Your all in cost is the fee plus the spread, and the spread mostly matters on thinner venues, so weigh both rather than the headline fee alone.
Do not forget the withdrawal fee
DOT withdrawals settle on the Polkadot relay chain, where on-chain fees are modest, but the fixed DOT withdrawal fee still varies by exchange. When you withdraw to self-custody, remember the existential deposit, the small minimum balance an account needs to stay active, since letting a wallet fall below it can remove the account.

FAQ
What is the cheapest exchange to buy Polkadot?
For DOT spot, the lowest base taker fees among the 20 venues FeeEdge tracks come from MEXC, Bitfinex and Backpack; Coinbase and Kraken sit higher. DOT is liquid on the majors, so the published fee is usually the main cost; also check your volume tier and any native-token discount.
What is the existential deposit when withdrawing DOT?
It is a small minimum balance the Polkadot network requires to keep an account active. If you withdraw DOT to self-custody, leave at least that amount in the account, because letting the balance fall below it can deactivate the account and remove any remaining dust. Your exchange withdrawal fee is separate from this.
