=====================================
Bitcoin Block Halving prediction
=====================================
bc=947208
gbt=1231006505
bbt=1777506318
This is average time to mine a block
(1777506318-1231006505)/947208
bts=576.9580029328268629204325
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 16 09:49:45 UTC 2028
-------------------------------------
Next palindrome will be 947749
predicted to happen at this time:
Sun May 3 14:27:32 UTC 2026
-------------------------------------
Current mining epoch number is 469.
The next fortnight happens in block
947520 and probably around this time:
Sat May 2 01:45:28 UTC 2026
