Insert second password to make payment and use VIRTUAL KEYBOARD ! Then, insert 2FA authentication (Google authenticator can help you) or you can confirm payment with a message on your phone ! Be careful about keylogger, it is so much dangerous !

The most important is use 2FA Google authenticator!
I have experience using 2FA in blockchain.info using the system via Message Phone and my btc still could be stolen, even though I put the computer itself, and used personally. And there is no any suspicious software that could steal my btc.

2FA is really not going to help you very much. I assume that you would be using blockchain.info if you are suggesting to use 2FA. If this is the case then you would still be vulnerable to attacks to your computer any time that you log in.

You need to use a computer that has never been connected to the internet to create the private keys and then use blockchain.info to 'watch' the addresses that you create. Anytime that you want to send money you should use a clean USB drive to sign the TX and push the TX with your computer.

Replace Microsoft Windows with GNU/Linux.

Concerned that blockchain bloat will lead to centralization? Storing less than 4 GB of data once required the budget of a superpower and a warehouse full of punched cards. https://upload.wikimedia.org/wikipedia/commons/8/87/IBM_card_storage.NARA.jpg https://en.wikipedia.org/wiki/Punched_card

Replace Microsoft Windows with GNU/Linux.

This is good advice. I only use my bitcoins when I boot from a live ubuntu operating system so it's clean everytime. It's too easy to get viruses and crap on a windows machine.

I recommend Tails, then make sure to dedicate the sole purpose of that machine to your wallet and NOTHING else.

There are many ways to protect yourself. I'd keep your coins offline in some way, but also only use a dedicated computer for your bitcoin transactions or like others have suggested use linux or ubuntu.

Only put a few bitcoin in your hot wallet  for spending. Never open links provided by strangers or from other unknown apps. Install antivirus software to avoid keylogger, trojan horse, virus etc.

Yes, let google rule the world! Let hem decide to have yourself access to all your wealth!

2FA is perfect, but not when it's dependent on a centralized entity.
What if they decided to block 2FA one day?

There is no best way for everyone. You can use a dedicated computer for bitcoin for a start. Do not do anything on it except sending bitcoin. No web browsing, no unnecessary software and no usb drives. Use only reliable internet connection and not free wifi. You can think about more advanced air gap methods later on.

What is meant by "air gap"?

It means the computer signing the transactions (computer with the keys) is never connected to the internet or any other computers. It is 'air gapped' between the computer broadcasting the transaction.

This gap is bridged by various methods, some use usb drives, some mentioned usb cameras and qr codes, so the computer with the keys cannot be hacked from internet.

I simply use a paper wallet. I have the skills to do the air gap and dedicated machine with the wallet but paper storage is much simpler. I do keep a little on hand in my desktop for day to day stuff.

I do something like this but with a harddrive.  The one has never been online.

Google doesn't have access to shit. I run https://github.com/gbraad/html5-google-authenticator airgapped to get my TOTP tokens.

Saying that you don't trust someone because of their behavior is completely valid.
