While the overwhelming trend of BTC is positive in the short to medium term, timing a short properly COULD be super profitable and the cost of those options SHOULD be lower than say in the stock market where the overall trend is less obvious. Can I ask what the option cost you @vlemon?
Certainly, the long term prospects of BTC are more hazy. While many coins do something different and better than BTC, who is to say they won't just hardfork those improvements into BTC?
NEM, with its all-original codebase and scalability into infinity has got my long term bet because all the coins derived from the base BTC code is likely able to be cannibalized by the leader.
