You are better putting at least half of it in Bitcoin. You may make more on alts but you can also lose the lot. 51% attacks are common. As market caps plummet coins don't have enough reserves to pay for their development (unless they have a very enthusiastic development team that is working for free). I think the market will bleed for some time. There may be an over correction where coins are selling below their raw cost to mine with the most efficient equipment at the lowest power prices before it goes up again.

Altcoins can make big gains but also can result in total loss. I certainly won't be guided by other peoples recommendations (trying to pump their bags).

Low market cap, good dev team, good real world usage and previous proven value is what I'll be looking for.
