bitcoin blockchain is being manoeuvred where its a 'reserve' and its altnets that are to be the 'currency tokens/iou notes.. 'coz too expensive to use bitcoin network'

the future is thunderdome: 2 may enter one may leave
people lock their bitcoin to contract vaults(locks) with some well established custodian/service

then play on other altnets using different denominated tokens(micropayments). offering faster services lower fee's or something.
then at the end of the month when its time to exit the altnet. bitcoin is too high a tx fee to claim the sats back

and so the altnet partner offers the value wishing to be withdrawn, but do so via a cheaper altcoin to exit the altnet (atomic swap)

like how banks offered people nickel, brass, copper in exchange for banknotes
altnet custodians will offer altcoin exits instead of btc exits. 'coz cheaper and faster'

and now the custodian hoards the sats and the person ends up with cheap altcoin
