I don't think you will see many seasoned vets complaining. Most of them are making money shorting BTC. They also know these swings happen. Its the new guys/gals who are not use to the market that complain.
Price swings are profit making opportunities for traders that know what to do. Great fun for traders but not so much for people who just bought coins.
Trade is gambling ........... all small trader will loss in long term ... like dice game that house edge never allow you be a winner a long term .......
Because of this %10 of traders are winner in the end .... These traders have so Money ,,,,, like million of dollars not like you or me with thousands of dollar........
