also we see network weight is increasing nicely

That would be wonderful if there was a dev here but with a no show dev and no updates I fail to see how network weight matters. Please enlighten me.
dev might be Oleg (freelancer) or Asphyxia himself, working on a plan we dont know but can imagine
there are heavy loads of $vidz in wallets
so ppl put their vidz from exchanges in wallets with 250 confs age to stake the hell out of it
supporting the network this way shows me there is support, watching them wallets getting daily filled up with vidz from market shows me there is a plan.
simple question: why top wallets buy more and more vidz, stake them and hodl in wallets?
