CEX vs DEX vs wallet apps — Why this matters

Control vs convenienceCEXs can be fast and simple, but they hold the keys and can freeze accounts. DEXs give you control but demand careful reading and signing.

Bitcoin seems to be a very promising idea. I like the idea of basing security on the assumption that the CPU power of honest participants outweighs that of the attacker.

Rules and recourseCEXs need KYC and can reverse or block certain transactions. On a DEX there is no support desk—your safety depends on your own checks.

PortabilityWhen you learn to drive a wallet (MetaMask/Rabby/Coinbase Wallet), those skills travel everywhere. If one app changes fees or terms, you can move without starting over.
