In the first first place mate, be observant while you're in the platform exchange then check how fast or slow when you are in front of the graph. Just like when you open Binance or Houbi you will see on these 2 platform exchange the top 5 altcoins which are moving fast or slow, now its up to you on which of them you are going to choose to buy in. then, once you have the coins apply day trade if you know how to do it. Because in making this methods most traders taking action when the price react in the graph chart. I guess you get what I'm trying to emphasize.
