=====================================
Bitcoin Block Halving prediction
=====================================
bc=958912
gbt=1231006505
bbt=1784566266
This is average time to mine a block
(1784566266-1231006505)/958912
bts=577.2783985617047636229772
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Mon Mar 20 07:16:40 UTC 2028
-------------------------------------
Next palindrome will be 959959
predicted to happen at this time:
Mon Jul 27 16:44:36 UTC 2026
-------------------------------------
Current mining epoch number is 475.
The next fortnight happens in block
959616 and probably around this time:
Sat Jul 25 09:44:29 UTC 2026
