there is no guarantee that your token will not rug...
Dozens of new tokens appear every day on pancakes and on average end up in a rug. I had a bad experience buying new tokens on pancakes because I lost tens of dollars there.
there is always risk of investing on shitcoin listed on pancakeswap, most shitcoin on pancakeswap i consider as shitcoin because only shitcoin & poor dev could listing their token there because its only cost about 10$ to get list on the exchange & extra liquidity ahaha
haha you must have encountered etherdelta, right? where all ethereum shittoken can be traded there directly, without a special listing process, although I don't think it's much different, but it's free right there. Very few of them will truly live like dogecoin, the rest will have only 1-2 years life span.
