Run a full node on some dedicated hardware that you won't have to mess with for several years. This can be done now very simply by flashing a second hand desktop computer like a Dell Optiplex with a 2-4T SSD and 16-32GB of ram with Start9 OS.
Running a full node is where so much of the power comes from. It is YOUR copy of the Bitcoin blockchain that you VERIFY your uxto set against.
You can connect your wallet to your node for mobile use and also view your server dashboard remotely over tor.
