seriously, I'm optimistic about crypto-currencies being one element of future products.
I'm less sure that any of the existing coins will be the foundation for that future time. Since it is #1, I own some bitcoins because they were cheap. I've already taken the money I put into the coins off the table, so the rest of the ride is risk-free.
You should not be too hopeful with your Coins, because coins are not to be expected. coins are counts that can be known up and down, experience and analysis is the main weapon to gain profit in the world crypto.
