Increase the price. I'm not sure to how much, but possibly to $20 or $50. Selling something for $1 hurts you more than it helps you because it attracts the "wrong" customers and also lowers the perceived value of the product.

I'm not sure if there is a market need (don't know much about Bitcoin) but you can't expect to find any customers without putting significant effort into marketing it. Maybe try content marketing, writing about Bitcoin security and how to protect oneself. One problem I see is that people may not be actively looking for a solution. People don't care about securing their wallet until (like you) they have been bitten by malware. Convincing existing Bitcoin users that securing their wallet is important seems like a difficult task because you need to educate them. That's the problem of being the first-mover in a market (I assume there aren't lots of competing products). If you have competitors they can do the educating for you.

If you don't want to put your efforts into marketing maybe just leave it there for a while. As Bitcoin becomes more popular it may well be that people come realize the need to secure their wallet. Maybe it's just a bit too early?

The interesting part of the product is that it can be useful even to people who don't own Bitcoin or don't personally care about Bitcoin.

Assuming that modern malware includes modules to drain Bitcoin wallets found on infected devices, and that any hackers will drain a Bitcoin wallet they find on a server they get access to, placing an unprotected wallet on any device should work well as a "you've been compromised" canary.

But marketing any security or backup product is difficult, because people start caring about security and backups only after they have lost their data once.
