Yes this is long term saving and it will help because bitcoin would have increased more in 5 to 10 years. But it would be good if the coins (I mean bitcoin) can be saved or hold throughout someone's entirely life and let his children still inherit it because bitcoin is an asset of value, its price will continue to increase undoubtedly.
That's correct mate. Bitcoin can serve as an ultimate saving tool and same time it can be profitable, but one will profit more when they invest for long term. It's not a get rich quick scheme if you are looking forward to get profits quickly. Businesses access crypto currency payment (Bitcoin), some invest in it while some just use it for day to day trades. Just saying that bitcoin has multiple purpose, it just for the user to know what's best to do with it.
