A 'Supernova' is a term coined by Tim Sykes, a penny stock trader who made a fortune during the internet boom on trading penny stocks. He states:
"An explosion in stock price that creates many opportunities to buy on the way up and short sell on the way down before fading into oblivion over several weeks or months. These can be triggered by anything: newsletter mentions, world events, message board hype, company news, etc."
I've never seen as many examples of supernovas as in various altcoins right now. It seems like there are multiple supernovas a day here. Keep in mind, people, these are NOT for the faint of heart. This is a .01 coin going to .10 and back to .01 in the span of 45 minutes. They are high precision, unpredictable plays that can end in disaster based on seconds/minutes. All crypto is volatile, but new release altcoins are the most volatile. In these scenarios, you don't want to try and sell at the peak because you never know when the peak is. You want to sell on the way up. For those interested in making money in crypto, that's a pattern to research for sure.
