5LTC too Too little 
5 LTC's a bit less
Topic: 1 ~ 5 LTC- Help me Create Genesis Block for My altcoin (Read 1259 times)
it's not az exact number. if your coin is popular, and there are lof of transaction, use high number. use block explorer to calculate the daily tr number.
but i think 8k is ok.
but i think 8k is ok.
thank you!!!
I met a problem again, I want to know the following line of code:
https://github.com/litecoin-project/litecoin/blob/v0.8.6.2/src/checkpoints.cpp#L58
8000, it is how to calculate.
what is estimated number.

Code:
static const CCheckpointData data = {
&mapCheckpoints,
1383887110, // * UNIX timestamp of last checkpoint block
2179203, // * total number of transactions between genesis and last checkpoint
// (the tx=... number in the SetBestChain debug.log lines)
8000.0 // * estimated number of transactions per day after checkpoint

Stop making crap coins .
true... true...
what's more funny - is to ask some questions here, where everyone is your enemy ))
I also want to have a altcoin... It even junk, I also want to have one.. 
Stop making crap coins .
Hi ALL:
I also want to make a Altcoin, however, I encountered a problem..
I hope to create a POS altcoin， I downloaded the ITC source code: https://github.com/information-coin/informationcoin
I want to create a Genesis Block,I hope to have a similar litecoin Genesis code, to help me.
Dear coders, help me, I am a poor student, I have 5 LTC, can give you
