I'm wondering why hasn't Monero taken off yet? Do you think government regulations have affected Monero's ability to go higher in price? If not, then what could be the reason? Is Monero a good long-term investment? Or are there better choices on the market (besides Bitcoin and Ethereum)? Your input will be greatly appreciated. Thank you. 
I have the same wonders. It's like they are battling a fight that is invisible. It's a good project and it has taken its flight before but there is just no hype for it "again". From year to year, there will be another platform that pops out of the blue and they are more recognized than the old coins who had the better project already. They just needed that bump of support.
IMO, Monero is a good investment choice but after buying it a little help might matter to drag it back up again.
