@Bagatell to check if it's "account" dependandat just create a fresh one give it a try. On the other hand to see if it's related to your IP/internet connection you should use another provider, using the data plan of your smartphone should do the trick.
Still can't connect to BCT so I thought I'd give Reddit a go. I posted here about Bitcoin trading and got no takers (no traders on Bitco.in forum?) so I posted here and got one reply from a buttcoiner. No traders on r/BitcoinMarkets either?
