Actually, RSAMMD is NOT the owner of TXTM. It is RSAMMDA LLC which reverse merged into TXTM.
If you think RSAMMD is the same as RSAMMDA LLC, then I would certainly recommend buying like crazy. But be aware that the ownership of RSAMMDA LLC is NOT exactly the same as the ownership of RSAMMD.
Conclusion: Buying TXTM is NOT the same as buying RSAMMD; rather, it's buying a relatively new company which to date has no actual revenue-producing business, only goals and plans (hopes and dreams).
