Yobit wallet again in maintenance mode since week. Asking when they will re-enable I got this reply from them:
Dear User!
Support answer:
Wallet is on maintenance.
The solution to this cryptocurrency will take some time, need to update the wallet.
We apologize for any inconvenience
Hopefully Novaexchange reopens soon..
I had a few coins that I sent to yobit 5 weeks ago when the wallet was on maintenance that got confirmed yesterday. This is very interesting because it means that their wallet was syncing blocks recently and therefore was connected to someone. The yobit wallet worked so well for so long it is sad. It might have something to do with the connections that their wallet is making. Yobit exchange wallets do not accept incoming connections and the nodes have to be hard-coded into the wallet. If the wallet that yobit tries to connect to is down, their wallet will remain down.
I run one of three seed nodes for genstake and mine has been constantly up and accepting connections all the time. Right now I have 13 connections on this node, all incoming.
Yobit has a long tradition of holding coins in maintenance for weeks and months, often these coins then get pumped while deposits and withdraws are disabled.
Also my genstake node runs perfectly stable since day 1. But if you also stake it takes up quite a bit of resources, I would say you need at least 2-3GB RAM dedicated to genstake wallet and also the staking does use a good amount of cpu load (like every staking coin!).
