I also think that having your own hardware to secure your data is the best solution, but you have to know what to do, and I've just scratching and start to learn these tools. I won't go into detail on the subject, I'm still a noob.
Running your own hardware isn't inherently more secure than using a competent, redundant, production network. It's very easy to screw things up if you don't understand exactly what you're doing. For 90%+ of the population, using a hosted cloud or installing your own hardware at a datacenter to host your own vaults and related server applications is the better option. Most people want a secure environment that works, not a part time job as a sys admin. If it's a hobby thing that you're doing to educate yourself, do your own hardware. But if you've $100k+ I'm bitcoin and the protection of those funds is your primary goal, then leave the engineering and administration to those who do it for a living.
