Welcome to the Governance Herd 
I don’t see meaningful liquidity for ITAM on other exchanges according to CG/CMC so I don’t see much point to staggering the sales. The price impact will be significant though so we can consider converting to ITAM-CUBE, at least for part of it, but we’d then be betting on ITAM-CUBE. Maybe someone can research what they’re planning to do with ITAM-CUBE and what base confidence level we can have that there will be liquidity for it in the future.
