That's very much true. Good time or profitable time to mine MASS was when it was not on exchange. Right now its price is volatile so we can see that complexity has also gone up. Its better to buy MASS rather then mine, its more profitable that way. Just my few satoshi.
What if in the future MASS will still be like now ? will you keep it or will you ignore it ? because everyone who is patient has his limit in terms of waiting and also has a target time that he must set for a profit on every coin he chooses now.
If you are HODLer then you can wait for your target price. See current price of BTC, if you have bought BTC at dip then you can enjoy selling it at its ATH. MASS is down right not but that doesnt mean it will be down for ever, i will wait until I see my target price.
