The principle of decentralization is not always applied in their DEX, they have previously held an initial dex offer (IDO) which requires Kyc to participants. They also monopolized coins in binancechain / bep-2 (cannot be used in other dex), and remain evidence that they are still obedient to centralization.
What you're saying is a crowdsale and not technically the usual trading. What OP is after is decentralization on trading without the use of KYC. However, could DEX really achieve high liquidity? It's near to impossible though.
