One strategy to build your crypto portfolio is as follows (just my personal take!!!),
tier one coins/tokens
BTC/BCH, ETH, LTC, Dash, Zcash, Monerotier two coins/tokens
NEO, XRP (even it is a banker's coin but its price should continue to climb), BCDtier tree coins/tokens
Electroneum, Ce-bit, Campus coin, Link, Walton
This is a Nice Plan I might start implementing this too.
When I get payed from my Steemit posts I transfer some of my SBD to bittrex where I buy those coins which are having a red day.
I might implement both strategies next time.
