I think riecoin dead. Gatra only gives 0.5 BTC. I think it is anything. Gatra must do everything and merge from bitcoin. Gatra says that he didnt any time for riecoin. Why poloniex has disabled wallet. I think somebody dont want other riecoins on poloniex. Because they sell their coins. I dont beleive Gatra.
polo disabled their wallet because there was a fork that went beyond the wallet limit, so they auto-disabled.
... now, that leaves the question why they haven't turned their wallet back on yet, but I suspect that says more about Polo's support, unfortunately.
