Bitcoin Block Halving prediction
=====================================
bc=942242
gbt=1231006505
bbt=1774495419
This is average time to mine a block
(1774495419-1231006505)/942242
bts=576.8033447847317517880207
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Tue Mar 14 12:43:13 UTC 2028
-------------------------------------
Next palindrome will be 942249
predicted to happen at this time:
Thu Mar 26 04:30:56 UTC 2026
-------------------------------------
Current mining epoch number is 467.
The next fortnight happens in block
943488 and probably around this time:
