I think the same.
Altcoin to me is just a way to multiply my bitcoins, sometimes all my bitcoins are invested in a few altcoins but in the end i sell all of them for more bitcoins.
Agreed.
Most people, along with myself, probably feel the same way, and use altcoins for the same purpose. The altcoin rate of change is much faster than bitcoins. While risky, the profits can present themselves much quicker than investing with bitcoin. But at the end of the day, all of that profit goes directly back into Bitcoin
