Just to add to all those information above.
In regards to ETF, if you already have an eToro account, I believe you can buy ETF as an underlying asset, not CFD.
Of course they will ask you to first sign the W-8BEN to be able to buy/sell US stocks

Most popular ETF for NASDAQ is QQQ
Most popular vanilla ETF for S&P 500 is SPY, IVV, VOO
If you want to save money on Robo-advisor fees and DIY your own ETF basket for diversification, just create your own portfolio using their (stashaway or mytheo or akrunow) % allocation or your own custom ETF basket
As always DYOR, happy investing
