I suppose it depends what your tolerance for risk is and how much of your overall investments are in crypto.

I trust one or two exchanges (Bitstamp and Bittrex). I trust Arrington's new crypto fund. I trust CME group. I trust Ripple (in so much as locking up their XRP goes and not abruptly shuttering the project 6 months from now because a founder got bored). I think Vitalik is the real deal (although I worry about what happens to ETH from an investment PoV if regulators start really turning the screws on ICOs).

Of course there's also a list a mile long of the crypto currencies, exchanges and ICOs I wouldn't touch with a barge pole :)

The gains at the moment are so large and so fast, if you have even $1K or $2K that you can afford to lose you almost can't go wrong. If you get even slightly lucky, you could likely pay that $2K back in to your savings account within a month or three and keep the remaining profits in crypto long term to see where it goes. The main risk is losing too much time to watching price tickers move on exchanges. That shit can get quite addictive if you don't keep a tab on it :)

Is there something wrong with coinbase/GDAX?

Don't want to get into a flamewar here (save that for reddit haha!) but they're not my cup of tea. Lots of people use them though.

My comment was in regards to actually shorting. Anything that is regulated like Nasdaq or CME I would trust. They will settle the shorting. Any other exchange could just disappear if there was major movement.

None of the exchanges I use support shorting. But yes, the limited shorting currently offered in the crypto world is not very robust. Fine for small day trader moves but no help with major movements.
