Think of MegaSerum as the big daddy of Serum. Basically, this is 1million Serum stacked together. MSRM is its own coin, and there are just 1,000 of them in existence. So, if you are lucky enough to own one, that would make you an instant Serum whale! To create one MSRM is simple—you buy 1million SRM and hey presto, you’ve got your first MSRM.
