My funds are in several different currencies and the transfer fees are now set between 5-11$ in all networks. How should one act in this situation, and should one suffer a loss and order all currencies with these transfer fees, or will the situation change?
If you wait any longer to see if fees will go down, you will be in trouble.
BitMart has already officially announced that they will stop trading from next 26th. There is a possibility that this platform operations will completely cease next year.
They have said that withdrawals will continue, but I could see that due to high withdrawal volume & manual review, many users got stuck. This is a similar problem with Bittrex exchange if I recall correctly. They turned off all withdrawal chain, kept ERC20 open, and would have deducted a fee of $50 for each withdrawal.
So, try withdrawing asap they open the withdrawal page. Yeah $5-11 fee is certainly annoying, but if the amount is meaningful, it is more reasonable to view that fee as a cost of reducing custody risk than as a loss.
