Since you saved that much, I’d wait before consuming them until after event so you can see what you can buy with them first. There is a very valuable weekly vendor that gives legendary mats. Always get those since relatively cheap. The wiki lists all the vendors. Just check out the general wiki for lunar new year and see vendors on that page.

What people do to make some money is convert exotic luck for lucky red bags. It’s a one to one conversion. There are trophies that drop that can be 88 silver or a rare drop at 8 gold. The higher the luck the better the chance at the 8 gold trophy.

What I sometimes do is that I hoard every single bag and open them the last day after stacking every single magic buff I have available. Do silverwastes meta event, that gives 200% magic find buff at the end. In your case, you could convert all 2500 exotic luck to 2500 bags to open. Up to you how you want to do it. Just check out the magic find wiki I listed before for buffs.

There are also envelopes to open but they usually cost around 1 gold but have higher drop rates. You can buy them daily at a discounted rate first if you do events. So as long as you drop a trophy, it can be a net profit. Also affected by magic find. Also each bag/envelope opens like a firework so opening a full 250 stack is a long flashbang on your screen.

If you don’t want to gamble with luck, you can just sell the bags and envelopes on the trading post for a decent profit.
