Personally, I would not invest in Monero. Yes, this is a good coin, but it seems to me that the price of this coin will not grow 2 times or more.
It went down 5 times, why off suddenly would not grow 2 times or more anymore? It will grow 100 times. and not that much into future.
If the price went down by 5 times, then there will be a solid reason behind it. Don't you think so? Unfortunately for Monero, it looks like other cryptos such as Zcash and Deep Onion are encroaching on its market share.
