The minimum fee to transger Bitcoin is 1 satoshi. It will take a while for that to get confirmed probably though so you can get it bumped up to have it confirmed faster.
It is just outrageous that people can really give such a bad advice to anybody. The author either knows nothing or is misleading the OP.
I had a few transactions recently and the MINIMUM I paid was 7,5USD for 300 byte transactions, BUT it took two days two confirm. I had a 1 dollar transaction only once back in December, but it was unconfirmed for more than three weeks.
If you create a transaction paying 1 satoshi, I can bet it will NEVER be confirmed, and it will cost you a lot of nerve and frustration and looking for ways to push it through anyway. Please know that currently the accelerators are either scam or they cost between 100 and 200 dollars per transactions, so it is better to inteligently set a fee that will be confirmed in reasonable time.
For that you can use this service:
