Yes, sometimes the numbers will be unrealistic but last time the price of NEO is very close to 200$ mark and GAS price is above 50$ mark. Many experts are saying the market is in a bullish mode which there is a chance for NEO to cross the value of 250$ in the coming bull run.
At least it is impossible to get to such a high price in recent years.Maybe we need to wait a long time.It is also possible that neo will never exceed the previous price.
It is not impossible to get the price and it must recover it's higher price in recent years and also it will create a new milestone of its price. Just it may take time to reach its milestone.
