Decent purchase, I especially like NEO, Qtum, and RPX. I think all of them will skyrocket in 2018-2019. However, a 24-coin portfolio is a little bit a lot as for me.
I hear ya...however, 80% of my portfolio is on the top 6 coins. The rest are hard core "speculations", cheap coins that may (or may not) amount to something. That is my "gambling" pot.
Believe it or not, 2 of my top coins (ICX and VEN) are from that group... just got promoted recently.
Investment in top coins should always be part and rest some % in speculative coins which if it rises can give you amazing returns and if fallen means your value of those coins would be next to zero. this coins are generally very cheap in price so upside/downside is significant.
