SO, they take much time to come to the real world market
Technically, they're already in the real world market as you can already freely trade those coins/tokens right now. What will most likely take time is the adoption, as most if not all the cryptocurrencies right now are still in the early alpha or beta stage like I said on my previous reply.
Yes, people can freely trade the coins and tokens but that doesnt mean they are being used to solve the real world problems. There is difference between trading of assets and use of asset to connect daily life problems or work with digital experience. I agree to the fact that most of the coins are still in the early stage of development and adoption of the coins will take time and it will also take time for people to understand the underlying blockchain technology and of what use it it. People currently are just seeing them as an asset to invest in without knowing of what use they really are.
