Understandably this network has a competitor (Arbitrum) however arbitrum doesn't have a coin, Both networks (Arbitrum and Optimism) are built to scale ethereum (solve high fees problems etc).

Optimism currently trading at $1.84 by the time of writing (feels a bit oversold).

Looking at https://coinmarketcap.com/rankings/exchanges/dex/ (Dex 24 hours trading volume) Arbitrum has second largest trading volume while Optimism is fifth.

So i was wondering if OP is nothing but a hyped up coin or is it good enough for the long term (3-4 years) ?

Haven't made much research either, please correct me if im wrong.
