4. Bitcoin is on only DCE's: Bitcoin is actually on both DCE's and CE's so it's falsehood to say Bitcoin is only on DCE's
Excuse me!
Would you mind giving me a full phrase, term of DCE and CE, please.
I never knew these terms but my guess is you are talking about Centralized Exchanges and Decentralized Exchanges. Correct me if I am wrong but these types of exchange are abbreviated as CEX for Centralized Exchange and DEX for Decentralized Exchange.
Correct your abbreviations, CE and DCE if you are actually mentioning about CEX and DEX.
