I just had a bitcoin deposit put into my holytransaction wallet.
Apparently they are having server upgrade issues. There is no warning when you log in or anywhere else. I had to do some digging to figure out they are having issues.
hadn't heard about this wallet until you mentioned it now, looking at the website looks a bit sketchy. Why would you such a un trusted wallet while there a so many good and trusted wallets for bitcoin. As far as your lost bitcoin go you just have to wait until they sort out problem and you will get the BTC if its not a scam.
