Your $1600 transaction took only 20 minutes to get confirmation with $0.68 fee
It depends on your client and familiarity, for convenience, use a 3rd-party client that will handle everything for you but most of them are inaccurate when it comes to fees and security risks.
BTW, do not discard the private key of 1AWndKv1HwVcwkUePKsf5FTa5Fe9qxnJpo yet, I've checked the other chains and I found out that it still has about <$100 value of different Bitcoin forks (BTG, BCH, BCD, etc).
Ex: $50 https://www.blockchain.com/bch/address/1AWndKv1HwVcwkUePKsf5FTa5Fe9qxnJpo Warning: BCH isn't any faster than BTC.
