Yeah I saw that too. Anyone who wants to invest in the long term (3-5 years) should be looking to drop some of their account worth into savings. Since Steemit is still beta, STEEM is gonna fluctuate, but imagine what's going to happen once mass adoption takes place. 

Looking back at it now, the laptop I have was a gift from a friend that was using it to mine BTC back in 2013, he gave up. My plan is to definitely keep a good amount of my earnings in the platform one way or another, and then to use some to make small investments in other cryptos. BTC, LTC, and now maybe XRP as well.
