I'm not sure what you are describing as incorrect. Tipping 100 Bitcoins would cost nearly $100,000. Yes, you can tip the same value in Bitcoins, but tipping a decimal amount is not fun since everyone is conditioned to local currency value that generally goes to 2 decimal places at most. Nerds are considering this. There is a big movement in bitcoin to denominate coins in millibitcoins or microbitcoins.
