IOTA has been above 20% for the past few days when I checked. I wanted to buy yesterday but I'm never sure if it's a good practice to buy when it's already that much up in 24 hours.
I'm not sure why but I feel way more comfortable buying when it's doing worse than 24 hours ago.
IOTA will be listed on Binance in the next few days, so only time will tell. Its seeing some resistance on Bitfenix at the .60 mark... excited to see what the added exchange does for how the price fluctuates.
