=====================================
Bitcoin Block Halving prediction
=====================================
bc=947445
gbt=1231006505
bbt=1777649631
This is average time to mine a block
(1777649631-1231006505)/947445
bts=576.9649415375652016051574
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 16 11:51:10 UTC 2028
-------------------------------------
Next palindrome will be 947749
predicted to happen at this time:
Sun May 3 16:17:08 UTC 2026
-------------------------------------
Current mining epoch number is 469.
The next fortnight happens in block
947520 and probably around this time:
Sat May 2 03:35:03 UTC 2026
