Now days people are running for bitcoin , etherum , litecoin ,dash coin, zcash & much more which are expensive. There are lots of coin which are under $1 & will give more profit in long run. According to my opinion top alt coins are below.
Ripple is used by bank. Everbody thinking that this coin will not rise up. but sure it will. Even ripple is moving very slow but very soon it will reach $1 .

Yes .. Digibyte is also sleeping giant. Even digibyte did not succeed in citibank contest. but next few months it will run like a bull.
3
Golem is super computer technology. Golem will also explod soon. Because its team is working very hard. Lots of people are not aware about this.

sia coin is another under value coin . Few days ago i buy sia coin it was just 560 satoshi and within 6 days it went to 800 satoshi. Im pretty sure will cross 1200 easily.

syscoin is another coin which is less than $1. So if you are beginner for cryptotrading go for smaller coin first which will definitly rise up.
Best of luck
