Not at all either do it through the CME, CBOE, or any other incoming fund or that will have tons of options for you. I don't want the two sides to mix lets keep it clean in crypto shall we 
thats true but you have to open a CME account, and you have to buy a short option, with a short token you can buy a percentage of it
bitcoin short would be something like tether, but not tethered on USD but on bitcoin futures, on short bitcoin futures also called put options
if bitcoin collapses in value these put options explode in value, many people say bitcoin will collapse in value, so why not creating this token?
