I would take ethereum for the full amount, and half of these funds I would invest in new ICOs. This approach should be beneficial, because if even one coin shows good growth, then you can make good money on it.
I would do about the same, only with a small correction. 33% in bitcoin, 33% in ethereum, and the remainder (34%) would invest in ICOs. I believe that in the investment portfolio it is necessary to have bitcoin.
