=====================================
Bitcoin Block Halving prediction
=====================================
bc=946729
gbt=1231006505
bbt=1777204324
This is average time to mine a block
(1777204324-1231006505)/946729
bts=576.9309296209056436365172
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 16 01:55:58 UTC 2028
-------------------------------------
Next palindrome will be 947749
predicted to happen at this time:
Sun May 3 07:19:53 UTC 2026
-------------------------------------
Current mining epoch number is 469.
The next fortnight happens in block
947520 and probably around this time:
Fri May 1 18:37:56 UTC 2026
