Hi,
Please let me know what are the requirement in order to create and develop cryptocurrency?
I need to know from the scratch
1. You can fork the code of existing cryptocurrency (code fork)
2. You can create your own crypto (probably by merging solutions from different blockchains)
3. You can create a hardfork of existing cryptocurrency
4. You can run a sidechain on one of the currencies
5. You can create a token on one of the existing currencies (ETH, NEM, Waves, NEO)
