Type 1, "I cant wait for the price of Bitcoin to rise so I can buy a new Lamborghini
with my Bitcoin."
Type 2, "I cant wait for the price of Bitcoin to rise so I can
sell my bitcoin and buy a new Lamborghini."
(Just want to clarify that the car isn't important in these two statements, but rather the Spend VS Sell)
Thus, in the 1st case you buy the car with BTC, while in the second you first convert BTC to fiat currency (paying the fees) and then buy the car with the fiat money.
The 2nd behaviour is quite stupid, actually
