=====================================
Bitcoin Block Halving prediction
=====================================
bc=958331
gbt=1231006505
bbt=1784238937
This is average time to mine a block
(1784238937-1231006505)/958331
bts=577.2868191816614701376975
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Mon Mar 20 09:44:02 UTC 2028
-------------------------------------
Next palindrome will be 958859
predicted to happen at this time:
Mon Jul 20 10:35:44 UTC 2026
-------------------------------------
Current mining epoch number is 475.
The next fortnight happens in block
959616 and probably around this time:
Sat Jul 25 11:59:10 UTC 2026
