Investing with ETF.

Hey r/investing.

I currently have around 5000€ into a saving account that earns me around 2% per year with no risk. My desire is to invest this money into ETFs related to S&P 500, as I'm willing to take more risk.

Problem is, as I currently live in France, can't invest into Vanguard funds (minimal 100.000€).

My question is how can I invest this money into ETFs with low transaction fees ? I read on bogglehead that I should open an account using a broker. IG Market seems to be the best where I live. As my bank is charging me around 8€ per transaction, IG Market will charge me the spread If I'm not mistaking ? Is it more efficient that using my bank ?

I'm willing to invest monthly into the said ETF.

I'm not talking about annual fees and taxes, just transactions ones. Paying for saving money is dumb.

Thank you !
