There are dedicated cryptocurrency creation services out there, from the likes of CryptoLife, Wallet Builders and Coin Creator.

They promise to carry out the technical work for you but, as Coin Creator notes, you need to have a precise idea for a project in mind, and display a level of interest and commitment that is “beyond idle curiosity”.
Otherwise, you’re highly likely to fail.
The real difficulties, however, lie in maintaining your cryptocurrency, convincing people that it’s actually worthwhile and has a future, and getting them to use it.
While you don’t necessarily need to have coding skills to set you own digital currency up, they’re vital when it comes to keeping it going.
