What do you use cryptocurrencies most often for?
I use cryptocurrency for trading, make a profit, exchange it into my local fiat. I repeat the process day by day, week by week, month by month 
If you thought about what cryptocurrency you use the most and what your favorite/most often use case is for it, what would it be?
I use bitcoin and altcoin at the most because that is what I use for trading and I search a way to make a profit in bitcoin. I also use bitcoin and altcoin for a very long-term investment.What would the websites be, or physical places you visit for your purchases?
I don't buy any products with bitcoin because I prefer to save more bitcoin right now. Besides that, I do not yet find any local website that accepts bitcoin as the payment.Anybody offer discounts for cryptocurrencies or anything special?
What kind of discount do you want? You will get a discount when the price of the coins is down because you can buy the coins at a low price.Special things you can only buy with crypto's or special discounts or anything, or just for the ease of transferring funds mostly?
I think the discount is applied in dollars and then we can see how much bitcoin we need to pay because so far, when I see the payment transaction of bitcoin, we don't make any discount or maybe I am wrong.I hope it answer your question
