So i am not 100 on how this all works, but do i also have to be watching out for what's on Sats that i receive?
As i have understood it, had it explained to me: An Ordinal is all extra data on each Sat?
no
the whole scheme is
that a guy is ranking sats.. (one scheme)
and secontly if you put a meme into the witness area of a tx that said tx also containts a rare sat EG "the first sat spent of a block reward(his ranking scheme).. then that meme is super super rare
his comments about "put into first sat"
is him defining a tx that spends the first sat of a block reward. it has nothing to do with putting data into the output value field of a tx
