=====================================
Bitcoin Block Halving prediction
=====================================
bc=941947
gbt=1231006505
bbt=1774314102
This is average time to mine a block
(1774314102-1231006505)/941947
bts=576.7914969828483100977973
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Tue Mar 14 09:15:53 UTC 2028
-------------------------------------
Next palindrome will be 942249
predicted to happen at this time:
Thu Mar 26 01:24:53 UTC 2026
-------------------------------------
Current mining epoch number is 467.
The next fortnight happens in block
943488 and probably around this time:
