Do you see a strategy where you sell SBD when STEEM prices goes up and buy SBD when STEEM price goes down? Have someone implemented it yet?
A: Yes, but its not so easy to spot this kind of price movements and when they happen they are very fast. So, it's sounds good in theory but not so enjoyable in practice.
A: However, you always want to have SBD when the price starts moving up, cause having less supply is better than having more in term of elasticity of the price (12.821.558 SBD vs. 254.092.069 STEEM).
My grain of salt. :)
