Currency trading

Is there any better way to trade for currency with other players than the trade channels? Having a bad time trying to pick up fusing orbs on Torment right now. Been spamming chat for about 3 hours now without success. Tried the usual 2:1 rate and even a slightly better rate of 11:6 or 14:8, no bites.

edit:
And right when I complain, I find a seller. Still curious if anyone knows a better way.

exilebro.com (yes, unfortunately another third party site to manage what doesn't work well in-game :/) - you can then contact currency buyers directly rather than hoping someone watching will be looking for your specific currency

There is also of course the usual act 3 merciless 'party' i.e. WTB fusings for ex.

I use the notice board in act 3 merci... works pretty well just look for the rate that best suits you and message them!
