First of all, you didn't spend any money on it. Only time, so whatever money you got is considered "free". You didn't messed up big time. It's just that, you did some mistakes and sometimes, making mistakes will make you a better one in terms of decision-making.
First mistake
I got introduced to the game early, like 2 to 3 weeks after the game was first launched, I ignored it seeing it as something more of a child's play,, I watched the number of players increased from almost zero to millions, I started to pick interest but still did not make up my mind to join, later on, I signed up but never played the game until about two weeks to launch, I started playing later on, I was able to earn around 7,500 Notcoins in total.
7,500 NOT has a total value of around 120$ as of this moment. Well, you got it for free and there's many new projects that's almost the same as Notcoin. Maybe try to do a bit of a research and join to all of them.
Who knows? One of them might end up like Notcoin or even better.
Second mistake
After the launch, I withdrew my 7,500 Notcoins to bybit, I watch the price rise to $0.012 but didn't sell, I was waiting for a higher price, eventually, price started to fall and it got to a point, I could no longer bear, I sold it all at around 0.004 for around $40 usdt, and like 4 to 5 days after selling, the price of Notcoin began to rise again, and today it's currently at $0.0226 per coin, my 7,500 Notcoin would have worth $170 now, but I gave it away for $40.
What a shame on me.. 🥺
There's always a 2nd chance for everything. You made a wrong decision by selling it at the wrong time, but all investors have experienced the same as you've done. I've sold some tokens in the past where that token pumped up a few days after I sold it. Don't be too sad about it. What's important is you got some money from it. Just invest that money into another token and let it grow. Making mistakes is pretty much normal for an investor to make. Learn from them so that you will not do the same mistake ever again OP.
