=====================================
Bitcoin Block Halving prediction
=====================================
bc=947047
gbt=1231006505
bbt=1777392662
This is average time to mine a block
(1777392662-1231006505)/947047
bts=576.9360761017392993808127
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 16 03:26:01 UTC 2028
-------------------------------------
Next palindrome will be 947749
predicted to happen at this time:
Sun May 3 08:41:11 UTC 2026
-------------------------------------
Current mining epoch number is 469.
The next fortnight happens in block
947520 and probably around this time:
Fri May 1 19:59:12 UTC 2026
