How to convert Stellar Lumens into USD I have created Stellar account. I have to transfer lumens to other account in USD.
How can I convert lumens to USD?

On stellar site, it is mentioned that we have create trust line with provided Anchors. But while creating thrust line it is always saying "changeTrustLowReserve".

Please suggest any inputs if you have.
What I'd suggest is to convert it to USDT on Bittrex or Bitfinex and then proceed to withdraw USDT to your bank account.

Another alternative is to convert it to BTC and withdraw it in cash using Localbitcoins.
