Don't think there'll be many answers to this. I mean how many crypto products can you use in real life lol.
Anyway i thought i'd post my own experiences with a coin you've probably never heard of. In the last month alone I've paid with Gulden at
The largest online pharmacy in the Netherlands. I do this regularly
A vegan restaurant in central Amsterdam (you must check this place out if you're vegan and in Amsterdam. Or even if you're not. ssooo good. On the Albert Cuypstraat where the market is is called Hearth Amsterdam)
A sushi restaurant in central Amsterdam (yum)
Paid for a raspberry pi for gulden witnessing (lock coins away and receive a percentage of the block reward)
Paying at a gulden merchant is really easy and the payment is instant through Nocks so no waiting for confirms etc
I tend to buy the coins back when I have paid with them or sometimes I'll just use my bags and wait although with crypto prices where they are i bought all the coins back from the purchases above
