On my site, I write often about the "BRED" portfolio - Bitcoin, Ripple, Ethereum, and Dash.
We have a mock portfolio - http://metacoin.com - where we have $2500 invested in each on January 1. Right now, that portfolio is worth more than $200K.
Underscores the need for diversification, and also the insane bull market we are in. (BTC is the worst-performing of the four, up only 131% YTD.)
Happy Trading!
