I am not sure if people will prefer to use Uniswap or PancakeSwap in the future. I believe people won't stop to use top CEXs like Binance, Kucoin, Coinbase, or Kraken because they have good features for trading and have big volumes as well. But people will be more careful to manage their tokens, they probably won't keep their coins on CEXs for a long time anymore. They are aware that keeping coins on CEXs is high risk, CEXs can have a problem at any time. They can't secure their coins because CEXs that have a full control to the coins.
Decentralized and centralized exchanges has it's own advantage and disadvantages and it will all depends on the user on which weighs more. I personally prefer using decentralized exchanges but I still use my centralized exchanges for some pairs and other things such as P2P trading but I don't store a big amount of crypto on centralized exchange given that there's a risk in it.
i can't left from centralized exchanges, it is my first priority than decentralized exchange, the reason of its some features,
such as i trade in p2p on binance and kucoin exchange,
it is a big advantages to use centralized exchanges even though cex is high risk instead of dex.
