How much they want u to pay before the update? I want to stress that the taxation being part of their business model is itself not bad for a coin. Whats appalling about it is that the fee procured through this machination is not shared with me. I also want a cookie. They just dont give me any money. I am a random guy yes but I hanker for being loved or better supported financially by someone else. I want to leech off them.
As far as I remember they are asking 0.5 BTC to update a wallet. Note that this was back in the days, like a year ago or so. I don't know if they are asking the same price today or not, things may changed. Anyway, the trick is that they don't guarantee that the wallet will work after you pay the fee, they will try to fix it and that's it. Again maybe things have changed, but I doubt.
bad exchanges are like that so no wonder, many wallets are not updated. It is better for you to send with other coins than you expect Yobit to do a wallet renewal
