165,000 BTC is roughly one percent of existing bitcoins in circulation. Depending on the schedule of the sales, that could cause a major disruption in the market. That's also four times the amount sold between last December and February. All of those bitcoins will probably hit the market in the course of 1-2 years.
The price of STEEM and SBD are quite tightly coupled with the cryptocurrency market in general. What this information means is that STEEM and SBD will probably not go much higher anytime soon. Things are probably going to pick up after the Mt. Gox bitcoin sale is over. Just steem on for the next couple of years and do not worry. With Smart Media Tokens and other positive developments, the value of Steem the blockchain will likely continue going up in the coming years.
