When you don't even know which blockchain to choose for your project then how you are going to develop the project as you promised.I will say creating your own blockchain is better than erc 20 token because it has very low chance of getting survival.
While is that creating just like block chain is better than a token?
Want to understand, can you throw more lite of this, because I think am misunderstanding something serious.
Independent blockchain projects are called as coins where as projects created on other blockchain like ethereum,tron,waves,etc will be terms as tokens and now tokens can be created pretty easily and to create independent blockchain will take efforts and then only you can develop the projects further more and can bring it into a successful path.
