You have to find a video on how to make altcoin videos on youtube and read articles about altcoin bitcoin. available at google
Far more than that..
FIRST thing you must do is secure it then maintain it's security for eternity.
Which if it is a public project that could be a rather large challenge for an inept kidiot by himself.
After all the security is the value of every coin owned on the block chain.
That is far more important than any features etc.
I STILL many years later find it amusing i am literally the only one smart enough to keep bringing up this glaring obvious point when it comes to noobs making coins.
It is essentially like leaving a retarded toddler guarding the bank vault of all your investment money.
AND being too fucking stupid to see you were not smart enough to even check the security.
Then and only then do you look at learning c / c++.
And since an idiot is asking.. he clearly has 0 skills in coding.
And clearly is going to get butt fucking raped by hackers eventually.
Why do i have to be the only smart one here ? (aside from a few rare guys like Bruno etc)
I'd be happy if at least one other person showed up at Bitcointalk that is not a raging imbecile.
It's lonely being the only genius here among a hair short of 1 MILLION forum accounts of stupidity.
Never mind the FUD.. nothing to see here guys, happy "investing" profiteers
