=====================================
Bitcoin Block Halving prediction
=====================================
bc=949834
gbt=1231006505
bbt=1779036667
This is average time to mine a block
(1779036667-1231006505)/949834
bts=576.9740660219932935720414
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 16 14:30:51 UTC 2028
-------------------------------------
Next palindrome will be 949949
predicted to happen at this time:
Mon May 18 11:16:59 UTC 2026
-------------------------------------
Current mining epoch number is 471.
The next fortnight happens in block
951552 and probably around this time:
Fri May 29 04:11:48 UTC 2026
