PIXFI decreased from $0.099 to less than $0.04. But now at $0.42. I can remember that NOT decrease from $0.000999 to almost $0.0004 but later increased.
About investing or not investing in the coin, you can use the money that you can afford to lose to invest in the coin. It is possible that the coin may rise or it may fall.
I was opportune to buy Notcoin when it was down and I made some good profits when it boosted back up in price, I recently bought some PIXFI at 0.038 and plan to sell at 0.070. I strongly believe it will rise again if I am patient enough. Besides the crypto world is all about leaping fate so I will just keep my fingers crossed and observe the market for now. I trade on Spot so I don't worry about liquidations.
