Many existing blockchain platforms can help you to create your own cryptocurrency – as a community coin, a joke, an actual solution to a real-world problem, or for any other reason. You can easily issue your own coin or token via:
- Ethereum
- EOS
- Waves
- BitShares
- NEM
- Komodo
- Nxt
- TRON
- IOTA
- NEO
- Cardano
- Qtum
If you don’t want to be dependent on any of these platforms, or they don’t offer the functionality you need, you can try to build your own blockchain from scratch.
Of course, the latter approach is much more complicated and requires in-depth training, code/programming skills, and fundamental understanding of the technology.
