In addition this fiat based custodian will have a lot of control and possible that they can alter the course of bitcoin's price. You don't have control of your keys, the custodian does and in cases like another split or fork, since they are the majority, they can choose not to follow that split or go on different direction. This is very dangerous for bitcoin crypto verse.
Its good news indeed but I don't think that we can sustain that growth, sooner or later those custodian starts their manipulation, and we will be affected in the long run.
amount of coins held is meaningless.
amount of USER nodes distributed is meaningless.
amount of hashpower is meaningless.
here is why.
core decided they wanted segwit. segwit got activated by threatening pools that if they didnt update to cores proposal. core nodes and businesses agreeing to core nodes will reject mining pools blocks.. and it didnt matter how much hashpower they had.. if they didnt flag acceptance with a version number. they would get rejected.
as for the node. there could be 50,000 nodes. but shill nodes are ignorable. the important nodes are the ones connected to services where people want to sell/user coins (merchants and exchanges)
so if a majority of merchants agree to only accept blocks of a certain version. then people will need to use the version and transact in a way that merchants will see(get) the payments so people can spend their coins.
it doesnt matter if there is 1000 user full nodes or 50000 user nodes.
if the main 20 exchanges and 50 merchants all agree to update to a certain version. then users and pools usually folow or find they cant spend their coins with those merchants.
it doesnt matter if a merchant has 1coin or a million coins. it know if it advertises it only accepts X version. people will use X version.
it doesnt matter if users have 1coin or a million coins. in a fork. they still have 1 coin or 1m coins. but now they have it on both forks.
this is why in 2017. under normal consensus segwit would not have got acceptance as it only had 35% approval.
but with the UASF and the NYA of merchants saying yes to a version of segwit.. segwit got its mandatory split date activated in august
and it had nothing to do with how many coins was held. it was a social cleanse and a bribe the popular USEFUL SERVICE nodes nodes
citibank is no threat. because. citibanks service is not an exchange people will be able to move their coins into. users wont see citibanks node/service as part of the network effect.
i would concentrate on what is known as the BSCartel . the group of core devs and the MERCHANTS that are working together and agree on everything like a heard of sheep. where by most exchanges and retailers who offer products and service for bitcoin operate.
