my wallet has 11 active connections, and is staking fine. I don't see a problem. I will try to send and receive to FreiExchange some tonight, and see if I see anything
Same here. Have no problems with the wallet. Wallet is sync and has 10 connections with the same block high as the explorer. I think it's all right.

Everything looks good, transactions from FreiExchange work, and are crazy fast. So that means, most likely there's no fork (my wallet and the exchange are on the same branch). Make sure your wallet is running the latest compatible version of the wallet (not a 3-5 old version).
HBN at 29Sat is a good buy. It's all speculative, but if there's another AltCoin boom, and HBN gets random push it could go back into the 100's or higher.
