Why you are going to confuse , because you should follow the simple way of the trading and use the basics of the trading in the altcoins .
As everyone knows trading ie unpredictable job , so to lower the loss you should choose multiple coins to make the trading more successful .
So here with these listed coin you should buy another also .
In my opinion the best coins currently to buy wre ATC coin , creva , xvg , pivx , psb coin , dgb coin and beside these coin there are nav and xev coin which are better to make money innthe future . Because these coins have good future and also chances of the increasing price are more .
So don't get late and buy multiple coins that you like to have and also don't forget to make analysis before buy any coin yourself because analysis are the main part of the successful trading .
