While we are quite approaching the Bitcoin dip against the halving, lot of Investors are already muscled up to dive in accumulating more to their Bitcoin holdings and those who had held the high cost of Bitcoin values as excuse is also being attracted to Invest without cost excuses anymore.
Firstly OP I see you use the word centralized blockchain, i would say you are confusing that word blockchain. Let me take bitcoin as an example there is nothing like a centralized blockchain. We have only one blockchain for bitcoin storage and all bitcoin in circulation are on that blockchain. Be it a centralized exchange or non custodial wallet the blockchain holds your bitcoin. On that blockchain, you can only move out your bitcoin only with the keys and the only difference between custodial storage and non custodial storage is that you are not given the keys (private key or seed phrase) when you stored bitcoin on centralized exchange addresses, so when the exchange goes down your bitcoin goes with it, if to say there you’re given the private key then you will have access to also send out from the address not through the exchange. So the blockchain is same and there is no such thing as centralized blockchain but rather a custodial and non custodial wallet
