> to actually make a transaction on the blockchain On which blockchain, exactly? On the Ethereum Mainnet you can transact for a fraction of a cent USD and it'll typically be verified (mined into a block) within a minute (often faster). On the Bitcoin chain you choose your own transaction fee, but if you're not keeping up with market rates your transaction might take quite a long time to be verified (again, mined into a block).
