Bitcoin will most probably have the role such as gold right now due to its limited supply (in the long term deflationary supply since people will be losing private keys). It's for sure good to have some Bitcoins safely stored away for the long term.
Don't panic. Bitcoin will recover in time, just hold for at least a year and it will be all good.
I would also recommend you to diversify and not keep everything in Bitcoin. You should add Ethereum and maybe some 3.0 blockchains such as Aion and Aeternity. More risk there but higher reward.
DigixDAO was gaining a lot during the crash. Ethereum and Aeternity didn't drop as much as others. I think AE will gain a lot this year, definitely worth holding.
Ethereum is showing a lot of promise. Unless Bitcoin does something about the transaction time and fees it might lose No1 place, the lightning network would be a nice upgrade.
Ethereum price stayed up during the dip because people had to buy ETH in order to invest in ICO. But yes I agree, Ethereum is for sure the best cryptocurrency at this moment. Bitcoin will need to do a lot of updates in order to start gaining again (if the lightning network gets implemented it's gonna be a step in the right direction).
