We will ignore the privacy issues. I am talking about the risks related to losing your money or accessing the private key.

I share my public key with a lot of untrusted third parties or unprotected devices. And the following questions arise in my mind:

If my computer contains viruses, is there a risk of modifying watch-only data and inserting a suspicious public key? I mean, scammer adds their address when I click deposit.

Incorrect new transaction sign request created. scammer will change my sign data request.

any other risks?

Can I create a transaction containing all Bitcoin address? P2PKH (1) P2SH (3) Bech32 (bc1)
If possible, why would the wallets create a separate wallet file for each address type or you can have one recovery file but all addresses are separate.

The other question is, can I send money from several inputs one of those inputs is an address containing 0 Bitcoin or invalid one?

Tokenized Bitcoin mean any way to use bitcoin on other blockchains or layer 2 or third part system as PayPal.
Bitcoin is viewed as a “reserve asset” or store of value that have top market Cap and slow network that have high fees.
Tokenizing is one of the solutions for anyone who wants to use Bitcoin and make fast payments.
we are seeing a growth in the number of BTC on Ethereum ¬ 180K BTC

Total bitcoin locked in lightning network ¬ 1.1K BTC

PayPal bitcoin purchases

Will we ever witness that we use Bitcoin on other networks more than Mainnet and how it will affect the market capacity.

I broadcast a transaction to make some payments and after a while I decided it was not worth it.  I double-spent it using RBF to my wallet address.
Does double spending using RBF reduce the privacy of wallet? can goverments/IRS/trackers know the addresses in my wallet because I broadcast that transaction, or is it considered safe as if I did not click on the broadcast button?
