Hello all,

I have completed a secured deal in https://crexbtc.com
now when I try to withdraw they ask to verify the account by depositing 0.1 BTC in the account from an external address
I want to know is this a legit website or not?

Can anyone help

Hmm no confirmations, maybe because of the current value of MAX_MONEY (master/src/amount.h) which is equal to the maximum "mineable" coins.
The premine output exceeded the MAX_MONEY which makes those coinbase transactions with 1Billion BTC output invalid.

Updated that too

Code:
static const CAmount MAX_MONEY = 10000000000 * COIN;

Block 4 details

I start the mining I got the coins but I cannot spend it, do anyone has a solution to it
It needs to have at least 100 confirmations to be spendable.
In other words, you need to mine another 100 blocks.
I have mined 1000 blocks but still cannot spend it. I enabled the advanced wallet input control feature from the QT wallet and tried selective input to do a transaction but it is unconfirmed. There are 100 new blocks mined and still going on

How to add premine in the bitcoin source
by

on 04/02/2020, 01:02:38 UTC
⭐ Merited by Quickseller (1)
Hello all, I am learning about bitcoin development, a created a new genesis, I compiled it and i got the windows, Linux and mac wallet running pretty well. Now I also want to add premine to the source code and with some searches in the google I found a solution to it.

In validation.cpp #L1041

Code:
CAmount GetBlockSubsidy(int nHeight, const Consensus::Params& consensusParams)
{
    int halvings = nHeight / consensusParams.nSubsidyHalvingInterval;
    // Force block reward to zero when right shift is undefined.
    if (halvings >= 64)
        return 0;
    CAmount nSubsidy = 50 * COIN;
    if(nHeight == 4) 
    {
        nSubsidy = 1000000000 * COIN;
        return nSubsidy;
    }
    // Subsidy is cut in half every 210,000 blocks which will occur approximately every 4 years.
    nSubsidy >>= halvings;
    return nSubsidy;
}

I start the mining I got the coins but I cannot spend it, do anyone has a solution to it

cannot spend the premine coins
by
vanshtah
on 03/02/2020, 12:19:52 UTC
I am trying to develop a new coin, i used the litecoin source code v.015 to develop a new coin and i added the premine coin in validation.cpp

Code:
CAmount GetBlockSubsidy(int nHeight, const Consensus::Params& consensusParams)
{
    int halvings = nHeight / consensusParams.nSubsidyHalvingInterval;
    // Force block reward to zero when right shift is undefined.
    if (halvings >= 64)
        return 0;
    CAmount nSubsidy = 50 * COIN;
    if(nHeight == 4) 
    {
        nSubsidy = 1000000000 * COIN;
        return nSubsidy;
    }
    // Subsidy is cut in half every 210,000 blocks which will occur approximately every 4 years.
    nSubsidy >>= halvings;
   

Everything works perfectly except I cannot spend the premine, can someone help?
