I'm big on BTC, Eth, Ripple, LTC, 60% then about 30% in NEO, XLM, EOS ADA, Monero, and OMG. Then I allocate 10% random altcoins.
In a bear market you need to strategize and buy into solid large cap positions. I suggest 30-50% in Bitcoin, 20-30% Ethereum, 10-20% LTC, 10% XRP/XLM then any other positions that you've reallly research and make sense during this dip. I highly recommend picking up any cryptos that you think have good fundamentals long term like NEO, XLM, EOS, ADA, Monero and Omisego.
Right now is not a great time to liquidate your holdings. If you hold long term you're more likely to take advantage of the market... we're still early in cryptocurrencies adoption to the mainstream.
On February 6 the SEC will be testifying during a senate hearing and discuss regulations. It's likely that this will help the LARGE CAP cryptos that are tried and true and have a lot of holders. The smaller ICOs will likely take hits from this sort of regulation, but regulation can legitimize large caps like Bitcoin, Ethereum, Litecoin and regulators love Ripple and XLM.
I'm reallocating my portfolio for defense in the current downturn. I don't see the bear market lasting long and I'm Dollar cost averaging this dip :
Bitcoin 30%
Ethereum 20%
Litecoin 10%
Ripple 10%
NEO 5%
XLM 5%
EOS 5%
ADA 5%
10% in Monero, OMG, ICON, DASH, Dragonchain, Tenx ZRX, QTUM, XVG, NAV, UBQ THC, BNB, KCS, LSK
