61% on BTC.
If we can go back to 51% that's 20B going into alts (hopefully not fiat).
We will see a big spike in alts.
I agree with other that the real alt spike will be in spring 2018
Most probably in spring of 2018, exactly just like what happened in 2017. There may be a pump in the end part of 2017 but it will not be like the one in the coming spring. Let us recall that in the spring of 2017, there was not only a bull run, there was high flying of the altcoins. Previous all time highs are surpassed for so many altcoins. And then for the remaining part of the year, such all time highs remain the same for many alts.
