LOL, you are not the only one, reading the content makes the reader to be more confuse, the title seem a bit sensible but the content is mixed up,
Maybe op is asking me if valuable tokens can be listed on uniswap or while project team should list valuable tokens on uniswap, whatever the question maybe, uniswap is a dex and that gives anyone the privilege to be able to list a token without too much stress like the ones associated with centralize exchange, and people provide liquidity in uniswap to increase volume,
Also even if the price of a token fall after listing on other exchange it is part of the market, it won't stay down for too long, plus the Defi hype is slowly dying down.
yes maybe he wants to ask like your statement, indeed Uniswap is amazing it can break into the market, immediately enter the ranks of major exchanges with all the conveniences the platform provides
