this is always a bad question.
and to find the answer you need to do it on your own, people here will only advertise the bags they are holding in 99% of the times!

and for trading just check altcoins that have a high enough daily trade volume and are not in a bubble.
for trade volume it is easy, just change the chart to 1 day charts and check the daily volume.
for bubble again on the same chart you need to look for a flat line or a big sharp drop in price to get it. when you saw a big sharp rise be sure that it is already too late to get in.

although there are a lot more, but what i said is the important part.
