bter paused NAS deposits and dgex have problems with NAS withdrawal (it is closing and I want not to lose my NAS there). Please do smth, fix the chain or what it is the problem!
I replied to the private message you sent me but I'll respond here as well.
I'm not aware of any problems with the NAS block chain. Looking at my public NAS node
http://funkyvps3.funkymonkey.org:7873/ things look fine. When I gain access to my private NAS nodes this evening I'll check things in more detail.
Without knowing what the withdrawal issue is that DGEX is having there's not much I or anyone else can do. If DGEX is having an issue with their node then resetting their node and re-downloading the block chain would fix the issue. If it's a peer related issue (can't find peers to connect to) then inform them that my public node can be used. It is open for all to see and abuse. If DGEX is removing NAS from their exchange and do not want to spend time trying to resolve their issues to process withdrawal requests, they can send their transactions to my public node as well.
If the other exchanges are disabling deposits then it's their own choice. I've sent BTER my contact details a couple of times several months ago and they have not attempted to contact me yet as far as I know.
I'm not aware of any NAS related blockchain issues so there's not much else I can do to fix an issue. If the exchanges are having issues and want assistance, have them post here and I'll see what I can do.
Also remember, sending any coin from exchange to exchange directly isn't a good idea. You should always withdrawal from an exchange to a local wallet then deposit to the next exchange.
