ETF's are not just for whales, you can invest into ETF's with just mere thousands as well, and if you think that a few thousand dollars is being a whale, then you will be shocked how many whales are there.
I consider a whale is someone who can put a million dollars into bitcoin without thinking, which means that he has that much cash laying around for something, it doesn't mean that he has only a million dollars, he probably has a lot more and he is only putting that much into bitcoin or it could be ETF for btc or eth as well. This is why I think we should be more careful with what we are doing, I believe that the best thing we can do right now would be just looking at our own investments and not watch what others are doing.
