I think there was a huge change regarding new crypto projects and their availability after launch. I still remember back in 2018 and 2019 and before of course, that new crypto projects had to pay really big amounts of money in order to get listed on "good" exchanges like Binance, Huobi, Kucoin and so on. So those big exchanges really had a lot of power back in the day. Once the whole Defi trend started and the first real Dexes like Uniswap and pancakeswap were created this all changed. Now all that a new projects needs to do is provide liquidity for their trading pair so they "only" need to have a reasonable amount of stable coins or ETH or BNB to pair it with their native token in order to be listed.
