I didn't invest in Bitgert because this is my first time hearing of the coin. I heard about Shiba Inu before it became popular but I also wasn't interested so I also didn't invest. Don't just decide based on rumors. It's right that you are asking for opinions here. But the way unknown altcoins are suddenly rising are always surprising. Just like with Shiba, I wasn't expecting that meme coin to suddenly become big.
What is Bitgert? Was it also a meme coin? if no then don't compare it with Shiba Inu or are you comparing it in terms of utility? I don't have any idea what is Bitgert I think you should give us a simple introduction on those two coins and probably the main website of each coins and you shouldn't be believing in rumors since they don't have any credible sources. I think researching and conducting your own opinion and perspective is much better than believing in rumors.
