Gas Fees? Am I doing something wrong…?

Hey Guys,
I am new to the Etherium network and want to buy into some coins here. I was using Binance Chain before.
I am using Metamask because everyone is talking about it for the ETH Network.
The Problem I have is I was trying to buy small Positions for some Coins. 100$ each to get startet.
And the Gas fee is estimated at 150$ is that correct or am I doing something wrong?

Thanks in Advance for your help!!!
