I suggest holding some BTC, ETH, LTC, and DASH. Also grab a couple cheaper coins that you think are going to do well and can profit big on in the future. When the cheaper ones hit big spikes and you can take profits then maybe trade again. That's what I started out doing after I lost some money trading and it got me back in the game, DGB made me very happy. I only trade a little when big moves happens in my holdings, I don't really sit and trade although I hope to after I feel more comfortable. I sell out, save some, watch em drop and buy back more or use it to buy up something else. For now if you do that you can sharpen your market reading skills. I'm not sure what you know or how you analyze that market but it's always good to learn other peoples strategies. I watch coins that I don't even hold just so I can practice applying trade strategies to them to see if I can make good calls.
Also my top recommendation on cheaper ALT coins to look at would be IOTA, check that out if you haven't yet.
