=====================================
Bitcoin Block Halving prediction
=====================================
bc=953583
gbt=1231006505
bbt=1781410153
This is average time to mine a block
(1781410153-1231006505)/953583
bts=577.1947180321817480159063
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Sun Mar 19 06:52:16 UTC 2028
-------------------------------------
Next palindrome will be 954459
predicted to happen at this time:
Sat Jun 20 00:36:15 UTC 2026
-------------------------------------
Current mining epoch number is 473.
The next fortnight happens in block
955584 and probably around this time:
Sat Jun 27 12:58:39 UTC 2026
