=====================================
Bitcoin Block Halving prediction
=====================================
bc=949747
gbt=1231006505
bbt=1778987481
This is average time to mine a block
(1778987481-1231006505)/949747
bts=576.9751302450755358263455
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 16 14:49:28 UTC 2028
-------------------------------------
Next palindrome will be 949949
predicted to happen at this time:
Mon May 18 11:33:49 UTC 2026
-------------------------------------
Current mining epoch number is 471.
The next fortnight happens in block
951552 and probably around this time:
Fri May 29 04:28:41 UTC 2026
