You think investing in btc and altscoins at the same time is kind of counter productive? They seem to be like a seesaw when one goes up the other falls so by investing in both you are always taking a loss at one end?
I would theorically (yet not empirically) think the opposite : if you are patient enough, and try to hold enough to buy low and sell high, on a long term perspective it's always a win. At least as long as there is a sufficient interest in digital currencies and blockchain technology. But just my 10 cents.
