I was using ionomy which has been down for the last week. That was the wallet address I was sending my Bitcoin to, then buying Litecoin (because of the much lower fees), then sending the LTC to hive-engine to swap for HIVE.
I started using ionomy years ago because people were reporting issues with sending directly from Coinbase, so I used ionomy as a go-between. But now they're down, and I can't use coinbase because they require the Plaid service, and my bank isn't on the supported list on Coinbase. Plus I think it's creepy giving plaid my banking login info.
