This thread is a little bit older now, but now certainly is a good time to be stocking up on coins/tokens that you see potential in. I have too many that I want to get bags of but alas, only so much money to buy them all! 

If using the $8000 like the OP asked, you certainly want to have a mix between large, medium and small caps. 

Small cap I'm (as some have also mentioned) mostly looking at Spectrecoin (XSPEC) as I see a bright future for it in the privacy space. Might take until 2019 or 2020, but I see it as a long term play specifically. 

Mid cap coins I'm looking at ENG, QASH, WAN, WABI, RHOC, 0x and some others.

Large cap at these prices are almost guaranteed to bring you profit with patience, just not as large of multipliers as the small-mid cap. EOS can be good to snag some free airdropped tokens, however there is always some FUD around it too, the good thing is it never really hurts the price.
