What is the minimum fee for Algorand?

I'm curious about the cost structure of Algorand. Could you please explain to me what the minimum fee is for transactions on the Algorand blockchain? I'm interested in understanding how this compares to other cryptocurrencies in terms of cost-effectiveness. Additionally, would you mind elaborating on any factors that might affect the minimum fee, such as transaction size or network congestion? It would be helpful to have a clearer picture of the costs involved in using Algorand for transactions.
