That's the concept... Eventually, the block reward will be almost nothing... Dust...
By then, the transaction fees should be enough to cover the mining expenses. If the fees aren't enough, most miners will stop mining, the diff will drop and the leftover miners will find more blocks, thus claiming more fees.
What (hopefully) also will happen, is by then a lot of coins will be lost + a lot of extra users will use bitcoin, so the price will rise exponentially, which is great for early adopters
I am trying to collect as much BTC as I can for that moment when it will come, hopefully it will come true, otherwise I would have lost quite a lot of time of my life collecting this amount of BTC for nothing if the price doesn't rise exponentially.
I know what you mean, i rarely spend any coin, but i try to do as much tasks in my free time to hoard BTC because i believe it will tenfold in price in the next years to come...
