Thanks again for the comments. I know very well that these are not new ideas that I come up with here. But I hope to develop features such as atomic swap and other things that can make my coin competitive. Well I'll think a little more before I decide.
You should look for the problems that are present in the already established projects and then try to solve those problems with your new coin, there are already lots of altcoins that are pegged to USD or maybe gold, so the market is already saturated for this niche. Like I said in the start of my post, search for a problem in the current market and find a way to solve it by implementing a solution through that coin built on either an established blockchain like the ethereum tokens or create your own from scratch(which would require more time and new methods). If you follow these steps then you can have a new coin with new features that are never seen before in the market.
