I use it as my savings, instead of storing my funds in the bank I prefer to buy coins and store it in my safe wallet then never spend it and just keep it as my savings. Having Crypto gives me full control of my funds without needing third trusted party like banks. This made me feel more secure of my asset and even expect greater return in the future.
We're same i don't buy goods online with my cryptocurrency instead i use it as my back up money in case my wallet goes empty then i can sell it right away. I trust it more than banks do with my secured money on them although i have banks also where my fiat money are stored there are still risks like system glitch that i experienced once.
