OK guys.. after carefully considering all of my options, I decided to purchase a hardware wallet. I made the order a few hours back. I think this is the best thing to do, given all the inconvenience I had to go through with the Blockchain.com wallet. Thanks everyone for their inputs! They were really helpful.
Great decision on your part! You didn't mention the amount, but considering the wallet was created in 2012, I'm guessing you're holding a significant sum. It's absolutely right to protect it yourself because, as every HODLer knows, "not your keys, not your coin."
