Re: is it possible to just copy and paste the bitcoin code?
In short words, yes you can copy and paste Bitcoin code and you may run your own altcoin. Just keep in mind it will call altcoin, not Bitcoin. Its because the chain will be totally different from Bitcoin, it does not have any relationship with the current Bitcoin blockchain. As you are asking about the BCH address, the best explanation has been given here, Why do Bitcoin Cash addresses look different from Bitcoin addresses? . They have added a new format of the address called CashAddr.
Aside on becoming an altcoin it wouldnt really get out some assurance that it would be adopted or would be supported by the community even if you do copy out Bitcoin code nd tend to market it out.It would really just be always be ending up on the position of being an altcoin.Dont know on what are op's things in mind but i do have those hunches.
