=====================================
Bitcoin Block Halving prediction
=====================================
bc=957580
gbt=1231006505
bbt=1783781146
This is average time to mine a block
(1783781146-1231006505)/957580
bts=577.2614964164911375643418
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Mon Mar 20 02:20:53 UTC 2028
-------------------------------------
Next palindrome will be 957759
predicted to happen at this time:
Sun Jul 12 19:27:55 UTC 2026
-------------------------------------
Current mining epoch number is 474.
The next fortnight happens in block
957600 and probably around this time:
Sat Jul 11 17:58:11 UTC 2026
