I don't understand why you didn't sell these coins for 20 cents. You can wait a long time for a good price or your coins will depreciate. I am selling coins in a bull market and I don't plan to sell anything right now because I have enough financial reserve.
Because at that point in my head it wouldn't change much, I mean I would have made 10x "invested" well more sinceI only bought 500k rest was mined ( and rigs were payed out years before ) but TBH i was perhaps kinda greedy, I wanted a bit more, my idea was to sell at 40cent, not sure why I had that number in my mind. When the next jump comes I just hope I wont make same mistake

Yes same thing happened to me with Ethereum and Doge. I thought Doge was going to $1 and did not sell at 70 cents. I thought Ethereum was going to $20,000 and did not sell at $4,800.
But the flip side to that is if you sold Raven Coin at 25 cents you would have had to pay taxes on $600,000! Or do you live in a part of the world where taxes are not an issue? All of the exchanges I know of that allow you to convert from crypto to local fiat are KYC so there is no way to dodge the tax issue.
Then again even after paying taxes you would be better off than hodling down to the bottom.
