=====================================
Bitcoin Block Halving prediction
=====================================
bc=949805
gbt=1231006505
bbt=1779025216
This is average time to mine a block
(1779025216-1231006505)/949805
bts=576.9796263658052275938454
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 16 16:08:09 UTC 2028
-------------------------------------
Next palindrome will be 949949
predicted to happen at this time:
Mon May 18 12:45:01 UTC 2026
-------------------------------------
Current mining epoch number is 471.
The next fortnight happens in block
951552 and probably around this time:
Fri May 29 05:39:59 UTC 2026
