I don't know about 5 coins but the top two coins to invest under $1 are Ripple and Remme. Ripple still can grow in the coming days but its growth is slow as its circulating supply is very high, on the other hand Remme is an altcoin which is still new in the market and has huge space for success. This coin will help to increase security levels, which is a stuff every company and user needs today due to which this project has 99.9% chance of being more successful coin in the coming days.
