upload picture, proof
you can't just accuse them like that
Ummm...What?
First, lets look at who we are talking about. If you don't believe that Yobit might have a wallet in maintenance making withdrawals impossible, you have never used yobit.
They have a horrible history of putting wallets in maintenance and leaving them that way... forever... or at least it will feel like forever, and not replying to tickets about the issue.
Second, for proof, look at the spacecoin wallet on yobit, and it says: Wallet status: Maintenance
As for this being a scam, the jury is out. Just cause they wont fix the wallet doesnt mean they are stealing anything... I assume the OP can sell the coins (assuming there are buyers) and cash them out as something else.
When a community suddenly revives a coin, anyone should be looking over the new code with a fine tooth comb before just running it.. so for yobit who takes forever to do almost anything it will take 10 times as long.
So, proof is not required that this wallet is in maintenance mode as its very common thing there... but if you need it, go to yobit space wallet and select withdraw. you will see it yourself.
I dont believe its a scam per se, but you may never be able to withdraw them from yobit, forcing you to sell them and withdraw some other coin.
It happened to me too, with a different coin... im sure there are lots of people who will say the same thing happened to them too...
