It's as safe as you are. I've been using DO for quite a while now, running droplets for DB, Web, cache (mem/redis) and plenty of other stuff, no issues - all downtime (maintenance) was minor and was pre-communicated effectively. You can manage your own SSH keys, software updates, and you can enable 2FA on your DO account. It's definitely safe enough, if you're safe enough. Happy to answer any questions, but tbh their support/docs section is some of the best on the web - I often find myself referring to some of their docs for non-DO stuff in my day job!
