What I can say is this is also an alternative for other layer-2 networks that we already have now that are still EVM compatible.
If you want to invest then expect that there will be no price of all-time high or how high it can go or how low in can dump.
I mean even though for L2 the market cap of around sub $700 million is kinda low but the hypes about manta has been gone, its never resurfacing again overshadowed by other L2 that just introduced their mainnet like blast and so on, i find actually manta might just be stuck at around this market cap and it will increase as the unocking goes, the fully diluted market cap is already high enough, the price will stay like this for a long time staying around $3-$4 assuming there's nothing crazy about manta going on in the future thats my speculation.
I personally already cashed out my investment when it almost hits $4 and will personally find another investment thats better.
