It is quite alarming that 60% of the EOS tokens are still not registered!
Only the Tokens that have been registered will be accessible on the mainnet.
If you are not sure if you have registered your address, you can use the EOS Registration verification tool on eosauthority to check if you are registered.
If you do not register your EOS tokens they will not be in the snapshot and you will lose your tokens.

The second tutorial is also very easy to understand.

You are in luck. Binance has confirmed that they will support the EOS MainNet Token Swap and handle all technical requirements.
