Yeah, no. 3 would be like Chase account, 4%, instant access. Of course it’s not my current account. My current account has no money lol keep just enough in there for DD and nothing else.
Index funds, it is the stock market but it is like Nutmeg except I don’t use Nutmeg, I use Vanguard. Better fees and more choices. As for which index fund, it’s like picking which company shares to buy I guess, which you need to do research on, there are a few popular ones and “standard”. All comes with risks but it’s a long game. It’s a 20, 30 years game. Not a 2, 5 or even 10 years.
I watch a couple of YT finance channels, Graham Stefan and Andrei Jikh, it’s mostly American orientated but the principles are the same. The latter one is very informative to get a grasp on financial services.
