I think litecoin will reach this price first, but i am not sure if it will be this year or next year.
At neo i can well imagine it, but neo will certainly reach the price only after litecoin.
Litecoin now are fluctuting slowly in the market so I don't think if they can reach the $500 value, but if they can touch that amount? I'm pretty sure that more investors are running and invest to that coin immediately.
None of them is going to touch $500 during this year, so just forget about that because it is not gonna happen, neither this year, or the next one.
Maybe if the market recovers, they both can touch $200, or maybe a little bit more, but it will take some months/years.
How can you sure with that speculation, maybe not this year but on the following year? who know what coins now from the altcoins family are reach $500? No one can knows what coins are climbing up to the highest.
