1. Have you ever used cryptocurrencies to buy something?
Yep. I used Ether to buy Bitcoin... If that counts...
2. Have you ever used cryptocurrencies to buy something from a physical store?
Nope
3. What cryptocurrency do you use the most?
Either Ether or Bitcoin
4. Do you ever regret buying something with cryptocurrencies?
So far, no. Since bitcoin prices shot up after I bought using Ether. But then again, ether also went up back then. so, I have mixed feelings.
Cool survey btw.
