REBL has announced they will get in top 5 in 2018 , they have now a huge community , a realy great daily volume , the project not yet started
REBL is also a good token but I don't think they can go far like that. Get into top 100 is possible for REBL but top 5 is totally impossible 
). IMO by the end of this year I think NEO is the only coin can be able to reach to #5 on the coinmarketcap or maybe even higher than that cause China is supporting for this coin. IOTA and EOS are also good but NEO is better.
