There are three kinds of bitcoin owner - those holding for the long-term, those looking to cash out into fiat, and those thinking that moving to an alt-coin will protect them from a large fall in value. While the former two are good ideas, the latter is totally pointless. All alt-coins track bitcoin more or less, and if bitcoin tanks you can bet your last dollar all the other alt-coins will too.
If you're thinking of moving to an alt-coin, i highly recommend you cash out into fiat or gold while you wait for this to blow over - at least if you're holding a substantial amount of money in crypto. If you think you're going to get rich buying bitcoin at $1500, you may be in for a shock when all "investors" pull out of crypto all together due to the extreme volatility and bad result.
I sound very anti-bitcoin. I'm not. But the truth is a lot of very rich and powerful people are looking to make cryptocurrencies fail, and this could be when they make their move. Take a couple of million in losses, but drop the market cap of all crypto by billions...
