nothing is impossible, it can happen.
however, it all depends on the market whether the more buyers or the more sellers, this year the development of all coin prices is a little slow, not like the previous year because the market competition is so big, especially this is a global business, everyone can join.
so I'm sure the Monero coin can also reach the price of 500 $.
Seems like that, Monero is a coin that is always fully supported by devs. so there is always trust from investors and Monero holders, but the price of $ 500 is impossible if the market is still like now.
