I disagree. The price of steem happened to go up at that time (by a lot) but that doesn't mean that you made a poor decision. In hindsight you can always find "investments" you could have made that had incredible returns but there's no way to know that in advance. That's why there's risk associated with these decisions. I'm sure I could have made millions if I bought some combination out of the money options on Facebook and twitter yesterday but if I had, in the real world there's also a chance I would have lost it all.
I'm new to steem and I'm a skeptic by heart so take that with a grain of salt but the way I look at it, it's like you're on a game show, you won $5000 and now the host asks you if you want to gamble it all on the next question or put half aside and gamble with only half . I know that I'm not going to win the $1M without gambling it all but I'd put half away every time. I think it's the smart thing to do...
