Honestly both are one of the most popular currencies facing the highest volatility however currently as of august 2022

Matic has faced insane pump inside this bearish market which i think we should be careful when investing to Matic in this hard time (it might dump very hard if btc goes 17k) i estimate $0.4 in that case.

Solana is currently facing hard time in this bear market all it does is drop and face some resistance in the bottom around $35.

Overall both coins are extremely risk to invest in (compared to other top alt coins)
