As time flows is it harder and harder to 'collect' (by collect you mean - earn?) bitcoins. We are not early adopters anymore, at least we are not feeling like ones.
Bitcoin is not magical asset which will accumulate in your wallet on its own, it is money - you can earn it, trade it, steal it - just like in real world.

In old times, you can mine bitcoin. Now, you have to buy. Or you can mine altcoin and sell for bitcoin. But that is not profitable most of the time.
