This sort of thinking is natural but incorrect since cryptocurrencies are divisible to many decimal places. It's just as easy to tip BTC, but tipping .00001 Bitcoins doesn't feel the same as tipping 100 Dogecoins, even though it's just as easy and exactly the same. It's just another one of those things that matters for adoption that nerds would never consider.
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.
