Questions about Hot Wallets in Polkadot (Talisman, Nova)

Question 1:

I see that Nova supports MYTH staking yet Talisman not, lets say I stake MYTH on Nova, yet I insert my seed phrase in a Talisman wallet, what happens with my MYTH staked?

Question 2:

What would happen if I have my cryptos on Nova or Talisman and by mistake I insert my seed phrase into a MetaMask wallet, what would happen to my cryptos?

Question 3:

Is it possible to send USDT/USDC or Bitcoin into my Nova wallet or what would happen if I do?

Question 4:

Can I stake my USDT in Nova wallet to earn interests and can I use it to buy DOT? If so how?

Question 5:

What would happen if I send ETH into my Nova wallet?

Question 6:

What would happen if Nova stopped supporting MYTH, what would be my options and what would happen to my cryptos?

Question 7

What would happen if my cellphone with Nova Wallet is stolen? Is my Hot Wallet compromised since Nova allows you to use a numeric password of 6 numbers, so eventually the hackers would guess the password by keep trying? Or is there a way to block the app from the thief if I enter into my account again?

Thanks for your answers.
