=====================================
Bitcoin Block Halving prediction
=====================================
bc=950647
gbt=1231006505
bbt=1779524581
This is average time to mine a block
(1779524581-1231006505)/950647
bts=576.9938778601543368312982
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 16 20:17:33 UTC 2028
-------------------------------------
Next palindrome will be 951159
predicted to happen at this time:
Tue May 26 18:26:41 UTC 2026
-------------------------------------
Current mining epoch number is 471.
The next fortnight happens in block
951552 and probably around this time:
Fri May 29 09:26:00 UTC 2026
