How to short an altcoin?

Is it possible to short an altcoin?

If you can find an exchange that supports hat feature. Otherwise, you could negotiate terms And a rate of interest with a current holder, though you'll need to collateralize it. Then you simply sell those coins and hope they fall so you can buy them back and return them to the lender.

Which exchanges support shorting?

Is there a service that facilitates that sort of an arrangement between a holder and shorter?

If there is none, sounds like an opportunity in the making.

Although if anyone knows of an exchange that shorts alts please post

Bitfinex and probably some Chinese exchanges.

I'm surprised a mainstream exchange hasn't set up a Stock Loan service...
They could just lend you coins from the Hot Wallet and charge large fees...
Instead these Rocket Scientists sell you "innovative" mining scams like Mintsy.

I can't find any indication of the coins that Bitfinex supports on their website.  Do they support any besides BTC?

Shorting shitcoins would be fine, just sell anything = profit. But it would kill any volume because nobody is so stupid to pump into shortly perma-sold coin. I often wished to sell overpumped coins shortly, but its not possible. Its not fair
