I think the key to remember is that the amount of SBD in circulation is so low. It doesn't take as many investors to start buying it for the price to start jumping. It is a simple lack of supply. When investors see it jump in price and more of them jump on the bandwagen, then the price just keeps rising.
I feel that the non steemit investors will want to sell of for profit at some point. This could cause the price to crash rather quickly.
You best bet is to either Steem up! by converting through the internal system or sell soon and buy a more stable coin... then by back your SBD on the dip.
I sold most of mine earlier this week for about $6 usd. I am not a risk taker so I was happy with that. Hoping to convert to steem when the prices level out (if they ever do)
I chose income over capital appreciation a long time ago. Steem Power is where it's at man. :-)
Do you mean having a future constant stream of variable cash flow as opposed to have inmediate FIAT on my bank? Would you please, expand on your comment "I choose income over capital appreciation", Thanks
