Trading altcoin is good but you need to know what is the best coin you invest to make profit you do research to know what coin jave potential to increase in the future.
The far majority of the altcoins are nothing more than empty projects functioning as pump and dump scheme -- how exactly will research help in these cases? If you happen to invest in these coins, or trade them, it will be nothing more than gambling. If you look at coin projects backed by real developers and a realistic roadmap, they are a far minority, and in most cases already bought up to their justifiable value. Result -- people will jump into pump and dump coins hoping to hit bank.
