I’m fairly new to crypto and many are promoting the various ERC-20 tokens out there
My question are they all using the same tech and if they are the same just different companies what new innovations do they bring?
Surely in this case people are just buying into the business plan of the company behind it, I.e Beam or Render and how they use this same tech?
Here maybe this article would give you an idea about ERC-20 tokens
https://www.investopedia.com/news/what-erc20-and-what-does-it-mean-ethereum/You can always check the roadmap and the whitepaper of each ERC-20 tokens to know what are the new innovation they could bring or offer to their investor. But you cannot rely to much on the information since some of developer just write some good plans but they would never execute it in real time.
So always choose those token which always follow what they have written on their roadmap or something that has good utility. Since those project have great chance to have more good development that is helpful to their token created.
