=====================================
Bitcoin Block Halving prediction
=====================================
bc=949423
gbt=1231006505
bbt=1778792974
This is average time to mine a block
(1778792974-1231006505)/949423
bts=576.9671600886432194678036
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 16 12:30:00 UTC 2028
-------------------------------------
Next palindrome will be 949949
predicted to happen at this time:
Mon May 18 09:27:38 UTC 2026
-------------------------------------
Current mining epoch number is 470.
The next fortnight happens in block
949536 and probably around this time:
Fri May 15 15:16:11 UTC 2026
