In the long term, most likely, but now it's not worth buying it, too expensive a price, it has grown significantly in recent months. Although who knows, can show insane growth, as it was with Blitz or NEO 
What the? how is now too expensive, it is at the bottom a long with all coins due to the Bitcoin slump. Now is the time to buy all coins that you want!
If this is really the bottom for crypto markets then it is a good time to buy. The noobs all got rekt and the hodlers are getting weak hands. But the question remains as to how low we can go...
I like XVG and I notice a lot of volume on the chain. Not sure what that volume is, maybe inter-exchange traffic, or maybe coin washing via alts? Either way, it's bullish.
