=====================================
Bitcoin Block Halving prediction
=====================================
bc=924143
gbt=1231006505
bbt=1763462792
This is average time to mine a block
(1763462792-1231006505)/924143
bts=576.1616014387368202358074
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Mon Mar 6 17:32:42 UTC 2028
-------------------------------------
Next palindrome will be 924429
predicted to happen at this time:
Thu Nov 20 08:32:54 UTC 2025
-------------------------------------
Current mining epoch number is 458.
The next fortnight happens in block
925344 and probably around this time:
Wed Nov 26 10:59:22 UTC 2025
