That can be a good thing.
I hoarded LLLL (Letter, Letter...) and NNNNN (Number, Number...) and let them go too soon, for $50-125/ea. (which was still a 100% ROI). In the Chinese market rush for these, they were going for 4 figures each, even more, if there were no 0s or 4s, and double+ 8s in the NNNNN. I dumped my LLLL/NNNNN before the market popped off, and during the rise, because I didn't understand it and thought the hundreds were the peak. If I held onto them and sold them as a portfolio, it would've been $250,000-$500,000.
I didn't even see the possibility of NNNNNN going for more than 20 bucks, but the same patterns reached $250-500 within a year from hand registration. I could've scooped up 500 of them and offloaded them for $175,000~, but I didn't have the risk tolerance to drop $3500 into an unknown.
