Shorting has a place and you've offered a good basic description. In crypto however it's such a risky strategy. So many people have racked up huge negative positions by letting a short run. In a market that is overall so bullish in the long run it's best to steer clear of shorting unless you're very risk-loving and have a great understanding of shorting and how crypto markets tend to operate.
I mainly agree with your comment, except you can reduce your risk of loss by spread betting the short side of major cryptos with brokers like IG index, guaranteed stops and placing short positions. Has worked well for those who have caught the drop on our trade floor in London. Also Spread betting is also tax exempt and comes under the gambling act so no capital gains tax on positions. Great thread on shorting, think the pro's and cons need to be made more aware to the public.
