Yes. To become a Baker you will need at least 8,000 Tezos - it's call a roll. To "bake" your own Tezos using your own stake, you would need to set up and host your own server node running both the node and baking software 24/7/365. It is highly advised that this server node has its own dedicated, unlimited bandwidth internet connection. You will also likely be required to own a secure hardware wallet and have it hooked up to the server node system at all times for added security. You will then be required to sponsor a 10% Tezos security bond to assure that you follow the Tezos "baking" rules. This 10% of your Tezos ownership could be lost permanently if baking violations or problems are detected.
