Is it possible to just copy and paste the bitcoin code and run it as your own bitcoin/ crypto without it updating/ syncing to the current blockchain.
If this is possible would this produce the key to the genesis block? I am very curious why you'd see bitcoin spinoffs like BCH have different wallet formats than bitcoin.
Ever heard of litecoin? It's not only possible, it's extremely easy. It shouldn't take even a script kiddie more than a day or two to figure it out.
However, most people caught on to this half a decade ago, so don't expect too much success. Even coblee has been taking a lot of shit lately on social media as I see people call him a scammer for the infamous dump from the ATH.
I think most people don't understand how easy it is to clone open source projects. Otherwise, the ICO bubble of 2017 probably wouldn't have happened and 95% of altcoins would have never gotten any attention.
