the list of dead Yobit wallets does not fit in one comment on this forum. they have a huge number of altcoins and about 90% of them don't even have a running wallet. and some of them don't even have a blockchain anymore because they are long dead and nobody mines them anymore!
you should really stay away from Yobit but in case you had no other choice at least check the wallet's status first. go to your account and in your wallet page click on withdraw or deposit, it will tell you the wallet is in maintenance for most of them so you can be 100% sure it is dead.
if it didn't say that, first deposit a small amount to test then deposit the rest.
This is true thats why this kind of post or piling up plans wont really be worth it at all. There are lots of stuck transactions in yobit this is why this exchange do really suck and most of the time you would really experience problems if you do make transactions on this site. Just like my previous experience on yobit when i was a newbie all the coins that i deposited on them havent reach my wallet on that exchange until now which do really suck.
