stability is always temporary in the BTC market, at least in this nascent era of early adoption. it won't be truly stable until the market is saturated and there is little room for future network growth. any long term stable period will eventually erupt into a violent trend.

regarding what to do, i'm of the opinion that we're approaching a major swing low in the $3000 area or maybe after a quick dip into the $2000s. the time to sell was in the $5000s. if you're going to sell this late, watch closely and don't wait forever to buy back.
