I honestly feel like most big whales on here understand and watch what people do. Do they power down and cash it out or do they hold on to most if not all and power up. That right there is a big tell tail for me if someone is going to take hive seriously and contribute to it's growth or just cash out.
It takes a huge amount of effort and time and honestly even after 5 years I still make hardly nothing and that's ok. For me you can invest, stake and earn in other methods with Hive and the blogging side is just one aspect of it all. That's the beautiful thing with hive now compared to a few years ago. You can earn MORE in MORE ways it doesn't have to strictly be about blogging and then hoping someone drops a big fat upvote on you.
Speaking of myself, I do check an account and behavioral patterns if I am thinking of supporting small fish. If they are sending it all out, why should I bother? Yes.. it happens.
Splinterlands, Rising Star.. two areas I have capital in. They both yield dividends on to me.
