Any fellow Eurofags here who can tell me if eToro is a good option for buying/holding/selling regular stocks? I don't want CFDs, Options, or any of that. I've been using Flatex so far but I'm tired of paying 10-20$ every time I buy/sell something, with US stocks being especially expensive.
eToro cliams they have no commissions for buying/selling regular stocks and I'm pretty sure that's either a straight up lie or I'm getting fucked bigly in some way I haven't figured out yet (Euros always get fucked) - I read the terms&conditions but haven't found the Jewish tricks yet.
Any advice would be much appreciated, I'm just so sick of commissions.

When the fuck are you supposed to sell? Clearly, I'm missing out on gainz compared to the people who make 100-200% on their portfolios but they seem to do complicated and time-consuming shit like options etc. (much of which isn't even allowed in my country or taxed up the ass), and I see just as many people lose most of their money.
I literally just come to this general once or twice a month, look up the latest memes on SeekingAlpha, and if the 5-10 year graph doesn't literally look like that of a PnD scam altcoin (many do), I buy a few shares.

Is it literally that easy? Statistically, how fucked will I be in 5 years if I continue not to sell any of my holdings?
