Was. Its a lot higher now, emeralds for example are 400+ %
Some tier comps fluctuate sometimes they reach 1k%.
I recently sld t0 for ~325k.
Took me a year to get to T10 with mine and I lost 250k in tt in the process.
Takes courage to go mod nano, especially in this economy, but I would not sell my T10 below 600k. Doesn't mean anyone will pay that but then again, there aren't many T10 available either. If there's gonna be a token-like event, mod nano will pay for itself quick so don't wait too long and get one, they're pretty nice
Hope this helps, good luck!
