Any news for SIA exchanges ?
I use hitbc and poloniex, both have problem with their wallet. Hitbtc still maintenance while Poloniex has confirmed but coin not shown..
Maybe you can try other exchanges (
https://coinmarketcap.com/currencies/siacoin/#markets), or do you have coins there that you want to get out? It's probably worth it to contact their support if you haven't already done it (and probably not useful to keep contacting them if you have already done it once).
