Top players from the traditional market need to get involved in cryptocurrency and issue decentralized products, the space need a lot of attention at this time.
I am just seeing it is not necessary. Bitcoin ecosystem does not need any top players from traditional markets. Because, when centralized things are working with the decentralized things that will lead to diluting the basics of decentralization concepts. But, when bitcoin will be proving its potential, top players will be joining for their own reason but people will never need to depend on them for any of the product they are offering by incorporating bitcoin. It means we do not need any such product but bitcoin will grow like anything else without need of any top players' interruption.
