Based on my research results, the altcoins that can reach 10-100x in 2021 are as follows:

1. ARPA
2. SHIB
3. AMP
4. CHZ
5. SRM

The five altcoins above are altcoins that have a very high potential to explode and skyrocket on coinmarketcap now. it's just a matter of time for all five to at least reach x10
