New to crypto, gas fees is a hindrance to get new users ?

Hello everyone,

As the tittle means, I’m new to crypto and I have a problem over it… I want to understand the gas fees.

To give you a context, i heard about a new project that I believe in with a development I like a lot. But I couldn’t buy this token directly through deposit: CHF -> Token.

As a new comer, i did install Metamask since I didn’t wanted to use a exchange sur as Binance etc.

I saw that ETH was “the thing” to buy first since it was “pushed” by Metamask even if I know other token exist such as BNB, Polygon etc. But since ETH is one of the most used for this kind of transfert (from my noob pov) I chose that one.

Once I have a my ETH on my wallet I was able to get quote to swap the token I wanted. BUT I saw an enormous gas fees, and I just don’t understand why. I know it has an explication that I want to understand… but I think this much fees can be a hindrance to new arrivals, as was the case with me and how can I avoid them next time.

And yes a read about the GWEI fluctuating but I don’t want to wait every Sunday morning to make operations.

Please can someone explain me why ETH has that much fees ?

Thank you !
