Bitcoin Block Halving prediction
=====================================
bc=964105
gbt=1231006505
bbt=1787729064
This is average time to mine a block
(1787729064-1231006505)/964105
bts=577.4495325202830394168276
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Wed Mar 22 09:11:31 UTC 2028
-------------------------------------
Next palindrome will be 964469
predicted to happen at this time:
Fri Aug 28 17:47:35 UTC 2026
-------------------------------------
Current mining epoch number is 478.
The next fortnight happens in block
965664 and probably around this time:
