Not only I have used it many times, I've even built a lightning network wallet (link in my profile).
You just have to look around and you'll see that millions of people are using it on a regular basis. Pure speculation can't make something become worth as much as Bitcoin is worth right now.
I would consider you wise then to use BTC for day to day activities considering you have used it many times. Did you use it to buy coffee when it was $60K and then use it to buy more BTC when it fell to $30K? Would you buy coffee with it when it is $150K or when it is $1 per coin?
Can we use Omni assets on Lightning yet? I havent checked in two or three years if anything besides bitcoin can be exchanged on that blockchain or state channel again
