You are stacking #Bitcoin but you have less than 1 and may never own one? Don't panic, it doesn't matter. Let me tell you why:
...
Owning 0.1 Bitcoin in 2044 is proportionally the same as owning 6.25 Bitcoin today. The block subsidy is identical in relation to ownership in both cases.
...
If you have 10% of 1 Bitcoin today, in ~20 years you will be the owner of an entire block reward, for which millions of people around the world simultaneously sacrifice their energy and time for ~10 minutes.
...
Your goal should not be fixed on a certain amount of Bitcoin, but your goal should be to be able to call the block reward of one Bitcoin block your property as early as possible.

All you have to do is owning some and hold.
