I will expect the transaction prices to go high as the prices of the coin go high as well. The transaction prices are also dependent on areas you are trading or agencies you trade with so you need to check the prices before you trade
The TX fees are basically the same across several platforms. Also using a low TX fee at this point means getting your transaction completed in 72 hours which is highly disappointing. In reality, Bitcoin fees has been same but the dollar equivalent is too damn high. It's hard to send a $5 transaction at the moment.
