=====================================
Bitcoin Block Halving prediction
=====================================
bc=902382
gbt=1231006505
bbt=1750653360
This is average time to mine a block
(1750653360-1231006505)/902382
bts=575.8606434296745395247915
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Fri Mar 3 01:45:56 UTC 2028
-------------------------------------
Next palindrome will be 903309
predicted to happen at this time:
Sun Jun 29 08:53:02 UTC 2025
-------------------------------------
Current mining epoch number is 447.
The next fortnight happens in block
903168 and probably around this time:
Sat Jun 28 10:19:46 UTC 2025
