Hi,
Really fun idea, I've decided to mimic you, but I'm 10 days behind, so missed the last uplift.
I'm having a few twists on your concept.
I started todo as much as possible through Bittrex, but there are 2 downsides:
1 - Minimum BTC trade is 0.001
2 - Not all altcoins are listed ofcourse

Due to some fund transfer issues, I've only managed to get 0.001 BTC of the the top 33 altcoins so far.
Still my 0.033 BTC spend from 2 days ago is now 0.0415 BTC as of now.

I'll will build out the portfolio in the next couple of days.

This should be more of a fun ride that just looking at one or two cryptos going up or down, even if the gains may not be as great and the losses greater.... but who knows, the reverse may be true.

Either way this is a fun way to play.
