I am a Tor newbie and considering deploying my own private bridge to connect to the Tor network. Normally I would connect to Tor via a VPN to prevent the entrance node from knowing my clearnet IP but after reading about private bridges, I am considering dropping the VPN method all togther. What are the benefits/drawbacks of using a private bridge over a VPN? For example security, speed etc... .
Also is it possible to chain bridges? For example
Bridge -> Bridge -> Bridge -> TOR
