Do u think xmr reaching 1000 usd is possible in 2018?
Try not to think in terms of USD but rather in BTC. If the cryptospace is a rollercoaster then all that matters is how close we're sitting to the front, irrespective of the nature of the track and its various loops.
I think xmr will slowly start to climb the top 10 again in 2018. There are too many scam coins at the top currently and we will see these finally starting to fall.
Monero is a great coin, infact the best there is for privacy bar non.
