The next better altcoins are :
1. ARPA
2. CHZ
3. TRON
4. MATIC
5. LINK
the five coins above are hidden unpolished gems in cryptospace, I am sure all five of them will explode and be able to reach and penetrate the All time high (ATH) price within the next 3 months at least, because looking at the projects of each of the altcoins mentioned above, all five have clear project goals, and the development team is very responsive and solid.
I am not familiar in ARPA, mind enlightening us about that project?
because i know the 4 coins and yes they are really promising especially Link and CHZ.
But tron is not hidden mate it has been mentioned in so many thread that this is waiting for a chance to make its way to ATH again.
