=====================================
Bitcoin Block Halving prediction
=====================================
bc=974525
gbt=1231006505
bbt=1793794684
This is average time to mine a block
(1793794684-1231006505)/974525
bts=577.4993986820259285026771
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Wed Mar 22 23:44:11 UTC 2028
-------------------------------------
Next palindrome will be 975579
predicted to happen at this time:
Wed Nov 11 13:22:48 UTC 2026
-------------------------------------
Current mining epoch number is 483.
The next fortnight happens in block
975744 and probably around this time:
Thu Nov 12 15:50:55 UTC 2026
