I prefer to be in BTC on this stage of market or USD. Alts are crazy now and IMHO they need a good correction now. And I think it will be before Cristmas. I dont want to buy overpumped coins now. That is only my IMHO. So u can find something interesting. For example, u can try to find something in low cap ICO's with hard cap.
I have always preferred holding BTC too anyway but it is always good to diversify. Some of these alts were really doing great and had some huge rise before the whole fork drama and then we saw a lot of them being dumped with BTC taking larger share of the chunk. I guess those moments are over now and they are all back to take their place.
If we do not want to see our investment crumbling down then I would not really advise going for doge. It is just a market being pumped. It is good to hold some of it though and I expect it to still do pretty well being an old coin. I cannot really say now if it would be a good move since you missed at the dip, but with BTC gaining dominance, some of them may reduce a bit.
