These are very good ideas. But, before anyone goes about building their apps, they should make sure that the idea that they have is a really good one and not just some project ideas that doesn’t make any sense. Because if you just keep on creating random decentralized applications, then no one is going to pick interest in it. So, it’s all about knowing whether it is something that is meant for you to get into. if you have a really good idea that you think would benefit the community and the people. Once you have a product that people would need, then it is definitely going to sell.
