Do not allow humans to pick your stocks. I recommend ETF index funds as opposed to Mutual funds. Mutual funds, or any fund that is controlled by humans, could morph into something else, i.e., whatever gets them the highest return. In an extreme example, you could buy a Green mutual fund only to find out later that it shifted a lot of its investments to fossil fuel companies. Index Funds pick a sector and follow it brainlessly. No broker or manager f#ckery.
Did the same thing. Got them using FOSS apps on Windows (Firefox, LibreOffice, Thunderbird), then switched them and made Linux look like Windows. They never cared, kept on using it like nothing changed.
