Fuck wish I seen this would they keep ltc wallet in maintenance since its not a small type coin
Withdraw it as much as possible, don't stuck your LTC's there and find a better exchange where you can trade not only with LTC but with different coins that you want to sell.
Yobit has a lot of coins and majority are shitcoins so I think they are really having a hard time making every one of them fully operational.
Most of those coins are shitcoins and very few coins that can be included to my list there but I don't want to spend my money and coins on that shitchange.
Just don't deposit while it's still maintenance because lot of noobs don't know that.
Just don't deposit if you don't want to have an headache, they have the worst support that won't help you during their wallet maintenance.
