Read GuideEvery exchange collapse and frozen-withdrawal headline tells the same story: if someone else holds your keys, you don’t really hold your crypto. Self-custody means your private keys live on a device only you control — so no company’s solvency, no hack, and no policy change can separate you from your coins.
The catch is that self-custody puts the responsibility on you, and the tools can be confusing. There are dozens of hardware wallets, half a dozen backup methods, and a lot of marketing noise. TerraCoin exists to cut through it: clear comparisons of the devices that matter, the real trade-offs between them, and honest guidance on backing up and protecting your setup.
