Does anyone here have a trading strategy where they look at functionality or the development team behind the coin?
Yes, of course there is. Such a strategy should require good analysis because then we will pay attention to how developers manage their coins. We must pay attention to all aspects that may affect the future of the coin. But back again to literally a trading, that is when we can sell coins that we have much more expensive than when we buy it then we will benefit. The main purpose of trading is to get a profit margin from the action of selling and buying coin.
