It's quite unfortunate and to be candid, issues of this nature are experienced daily by people in the cryptocurrency space. Most people can relate with this and that's how we gain our experience. I'm so sorry for the sad experience but that doesn't mean you're greedy, you were only trying to get best out of the market and that's what most people do.
When we're trying to get the best from the market, we don't intend to make things worse but only the best of it. But, some events really are turning things from our expectation and making things go unplanned.
You only need a miracle and some whales may try to pump it up. The last thing that you said is correct however there are still people like the op who are tempted to ride a moving train. Some of them are already lucky to earn but they got greedy and expect for more so what they receive instead is a bad karma or a loss.
That happens when you're not satisfied yet with what you're seeing despite that you've made a profit already. Still, you want to insist and go for more as you try to make money from it.
