At the moment, most of my money is in bitcoin. I need to pick up trading again to be honest, but at the moment I prefer bitcoin, that way you don't have to worry about losing large sums of money because of some crash of an altcoin.
Monero and Dash seem interesting ideas but I'm not convinced enough to buy, bitcoin is too far ahead.
I debated shorting DASH but don't really like the anxiety margin trading gives me. Sold out my XMR holdings so now I currently hold just BTC and ICONOMI. Debating if I want to invest more in Iconomi, but have a feeling it's going to take a dip pretty soon.
