You can lose profit sending trading and withdrawing if you are trading a small amount I have $50 worth of Ferum or FRM it will take $6 to send the whole amount to Bilaxy and after you trade it to Eth and wants to withdraw it you will have to spend $12 to withdraw your Eth,
now that's $18 gas fees for your $50, my only option is to trade it to other altcoins like DGB or Litecoin which offer $4 to $5 fee you still going to lose $11, that's over 20%.
Choose the option that saves you from fees since you're likely to cash it out from crypto and taking it to your bank account. It's not wise to choose Ethereum this time as a means of transfer because we're all aware of the fees but we have no problem with the transaction time because it seems still reliable but not quicker than before. You have the other choice to make the transfer pay fewer fees and that's why traders are adaptable based on the situation that we're facing if fees for ETH or any other altcoin went higher.
