something that is centralized is not good for crypto, because centralized control can actually cause FUD or even hacked as it had before. centralized coins also suffer the same fate, although not about hacked or fraud, centralized coins show less signi fi cant strength compared to decentralized coins.
you can not have full decentralization..
some centralizaton points are good for growth and evolvement of the crypto space
also custodian services and exchanges are the ones who make the ecosystem go forward more than anything!
