Saving Bitcoin for a long term horizon actually reduces the risk. If you’re quickly trading in and out in the short term then your risk is increased. Although you make a good point about storage. Exchanges aren’t trustworthy and cold storage is a difficult concept to get through your head. On that point, I agree, Steemit is better than exchanges, but it’s still a hot wallet! Also the reason I suggest Bitcoin is due to the deflationary effect Bitcoin posses to level out your inflationary effects of holding STEEM! Thanks for the comment!
