I think it's going to start coming in more useful when the update comes out. At the moment I'm not spending anything as the last year I've pretty much collected every item (unorderable at least) in game. So mine is just building up with not much to do, since I was saving for a colectable that's no longer available. I will either use it to obtain new villagers when the update arrives, or any new furniture, or just do a giveaway. I do/did want tbt, but like I say, it was for a collectible but it took too long for me to obtain the amount
Yes. It's like asking, say the UK, do you still want pounds? Without it, the place would be dead. It's a currency; here on Bell Tree Forums, we use it for collectibles, art, villagers, and in game items. In real life, we use it for bills, food, you get the point.
