=====================================
Bitcoin Block Halving prediction
=====================================
bc=949008
gbt=1231006505
bbt=1778540543
This is average time to mine a block
(1778540543-1231006505)/949008
bts=576.9534725171204909542480
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 16 08:30:28 UTC 2028
-------------------------------------
Next palindrome will be 949949
predicted to happen at this time:
Mon May 18 05:50:56 UTC 2026
-------------------------------------
Current mining epoch number is 470.
The next fortnight happens in block
949536 and probably around this time:
Fri May 15 11:39:34 UTC 2026
