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.
TRON and LINK seems to be reasonable to expect but those 3 other mentioned? they seems to be a shitcoin for me though Matic is one of the talk in our group early this year but this fails the expectation and now continues to dump.
for OP? please invest with your own diligence because no one can save you from losing but your decision only.
