=====================================
Bitcoin Block Halving prediction
=====================================
bc=947771
gbt=1231006505
bbt=1777841854
This is average time to mine a block
(1777841854-1231006505)/947771
bts=576.9693016885917710166580
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 16 13:07:28 UTC 2028
-------------------------------------
Next palindrome will be 948849
predicted to happen at this time:
Mon May 11 01:43:46 UTC 2026
-------------------------------------
Current mining epoch number is 470.
The next fortnight happens in block
949536 and probably around this time:
Fri May 15 15:50:04 UTC 2026
