I don't know what happened, but I also lost significant amount of BTC a few times in the past and started obtaining from scratch. My current advised setup is this: 3 different harware wallets from multiple vendors, generate 2-of-3 multisig. Send some money to the address, try to send back money with any 2 of the 3.
