Yes, $up does actually go up only. This is because of its unique system which is known as "Diamond Handing". This system works by having believers buy and lock up their coins, and then they are forced to hold them for a certain period of time. This effectively prevents them from selling and driving down the price, ensuring that the price of $up only goes up. This system has allowed $up to do a 70x increase since its launch, making it one of the most successful coins in the market.
