Hi! Yes, many players buy ingots. They usually go for a rate of 500 bits to 1 ingot (so $250,000 for your 500). Sometimes they sell for more or less, depending on who's buying.

I tend to buy them at the rate of 500:1, so if you want to sell just set up a private trade. Otherwise you can set up a public trade to see if they'll sell at your preferred rate.

Generally the 500:1 is the average max most players are willing to spend. Anymore is overpaying in my opinion. Sometimes people will sell them for less, 300:1 usually lowest average I see. Any less is a steal. You can go with whatever feels right for you. Anywhere in that range should be easy to sell
