Whoever 'recommended' Tether is a complete twat. It's not designed for dollar extraction, more value parking. The only place you could get real dollars for that would be swapping from Tether to USD on Kraken, and their dollar transfer options are hopeless, or Bitfinex and their banking might be screwed.

I would go for Gemini myself - https://gemini.com/areas-of-operation/ but make sure you request active trader status from support as you get much better fees. Or a very trusted trader on Localbitcoins.

And it may not be fashionable but I'd never sell to anyone on here under any circumstances.
