Ravencoin
XLM
ICX
ZIL
STEEM
Enigma
Polymath
Ox
Civic or TKY
HPB
MAN
REN
TOMO...
These are just some of the projects, I think are very solid under $1
It looks like you dropped the XRP and ADA. Why are the two altcoin not listed? Replacing REN and TOMO, your cryptocurrency investment list under 1$ would be great
