Why do you think that $OM can't do it again?
It has more developed infrastructure and more utility compared to the times it was at 0.3$. Furthermore, it is more regulatory adjusted, which even $BTC can't be so proud of.
MANTRA exists 5+ years, and they could rugpull at 9$ or a long time ago. Why would someone destroy the coin that they were building and developing for so many years?
I will not beg you to buy the coin, and I will not suggest you hold it. I will also not try to ensure you that it is not a scam. It was not proved yet.
I'm just curious why you think that something that happened once can't repeat and why everyone is telling that the rise to 3-6 is impossible?
If the coin is not a clear scam (which is also possible), it can rise again within 6-18 months. Of course, if the team will work on their mistakes.
If you want to sell it, give ahead, no one will stop you, but if you decide to hold it, just hold it, be patient, and don't create more panics and rumors. With creating panics, you shoot your own leg. However, it's already worth nothing, so you would not lose more.
P.S. It's funny when people who invest their last money in memecoins and wanting to get millions in a month are 100% sure that such old coins are a clear scam.
