i just like to keep everything in btc,makes it simple
So this means you exchange FIAT into BTC and sit on them?
It is the best thing to do. All the other coins change with bitcoin so it is rare that can be earning something with the trade of the other coins.
I have been holding Maidsafe for a long time now and some Monero as well and they seem to go on it's own so they serve as a good alternative investment when BTC goes down. Of course if the BTC downtrend is big, then forget it, BTC is too strong and will make the crypto market in general go red as well. I recommend a small diversification of your portfolio in a couple alts of your choice, not more.
