=====================================
Bitcoin Block Halving prediction
=====================================
bc=957261
gbt=1231006505
bbt=1783571417
This is average time to mine a block
(1783571417-1231006505)/957261
bts=577.2347716717053429468630
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Sun Mar 19 18:33:12 UTC 2028
-------------------------------------
Next palindrome will be 957759
predicted to happen at this time:
Sun Jul 12 12:21:19 UTC 2026
-------------------------------------
Current mining epoch number is 474.
The next fortnight happens in block
957600 and probably around this time:
Sat Jul 11 10:51:39 UTC 2026
