at market that time illegal hnc.G is around 500-700m, so buying at 1,5b-2b its consider normal, when you refine your self ytolo +10 and use astb1/2 to +11 then +12 using few vstb,
and selling price sometimes lower than the actual cost you using. consider , want sell fast/ change equipmenet.

why at that time 3 months ago gm not do anything? and just by now gm do something?? there is still lot hnc .G/DG/Xg ilegal around and people keep safe, why not wipe all the ilegal
