I find the current trend is to hold coin worth, trading habits should change because it is really complicated and difficult to bring profit, stay away from the ponzi model and lending ico. That is my advice, and you, see the current trend like? 
Wise advice.
Indeed so far Holding is the best strategy, in spite of that we should make a buy according to the type of coin we are holding this's done solely for the value we expect can quickly materialize in the future.
Trend is in between positive and negative now. There is no certain thing yet. Rich whales will determine the next trend this week, we will see, that's it for us. Prices are changing very fast.
