I am using cryptocurrency at least once a week for various online services, simply because it's more convenient and also more private, cheaper and faster than using regular FIAT options.
How do you mean here?
Well, cryptocurrency is not cheaper than fiat if i may say correctly, you can convinced me that it's more convenient while using it at your home without you having to move out to any center or using third party system to process your payment just as fiat. You know to process payment online or offline there is always an third party over there, but with cryptocurrencies you are permissionless but still it's not cheaper than fiat as you made mentioned here.
Of course I uses bitcoin and other coin for trade and also sell out to fiat coupled with using it to gamble, so i can't say i don't use cryptocurrency for my day to day activity and even though it's not regular but at least used it to gamble/trade.
