=====================================
Bitcoin Block Halving prediction
=====================================
bc=947348
gbt=1231006505
bbt=1777593025
This is average time to mine a block
(1777593025-1231006505)/947348
bts=576.9642655452214548176015
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 16 11:39:20 UTC 2028
-------------------------------------
Next palindrome will be 947749
predicted to happen at this time:
Sun May 3 16:06:27 UTC 2026
-------------------------------------
Current mining epoch number is 469.
The next fortnight happens in block
947520 and probably around this time:
Sat May 2 03:24:22 UTC 2026
