I read technical analyses and avoid speculative ones and don't take unnecessary risks, sometimes even doing nothing would be very good move for me.
Normally, the knowledge on technical analysis can really assist a long way when it comes to trading the altcoin market, but also, a lot of experience need to be gained so as to be able to know what makes the altcoin market tick and move in most cases which is why the knowledge and practicing a bit for a while until one is able to get one or two strategies that works well and able to take the right step when opportunity kicks in the market. The likes of tab traders, crypscan are good tools one can make good use of.
