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.
I would like to believe, but it seems to me that this will not happen. Maybe I'm wrong and it's worth part of the money to invest in Monero, but this is a personal decision of each person.
