Crypto is user hostile then? Got it
Nope. The point is you store your crypto on a non-custodial software wallet (Metamask) or a hardware wallet (Ledger Nano) and not on an exchange, so it cannot be 'held hostage' . It is not your keys, not your coins if it is on an exchange which uses custodial wallets, but doesn't apply if it is on a non-custodial wallet.
Your funds are spendable by your private key. Your private key is stored on Metamask, Ledger or a piece of paper.
It’s an important distinction to make. Your hardware wallet is just a custodian of your private key.
