Agreed, its better to invest on the strong project like Ethereum or BNB for early crypto investor. After that he can try to surf on the market to decided what he really want to invest, he also can ask about the prospect of its projects here.
Only new investors should ask experienced investors, because old investors will always use their time for coins that can be very suitable for the long term as you say, because they are also very tired of doing various analyzes and the research they need.
