Does solana network ready for huge demand?
I can not be sure of this, some few weeks back, there was network congestion on the network.
So i think we see 7000$ price because supply and demand but even that much gain it's not life Changing gain so that's why i don't try to get rich with alt coins neither with btc but it's nice to some gains.
$7,000 is too high a target. Certainly not in this bull run. Even Ethereum hasn't reached there yet and if you recall very well Ethereum was way more popular than Solana

Don't have your hopes so, you will be disappointed
Was that too high? I think their ATH is around $200 maybe a conservative reaches of $300 could be tolerable but at $7k not so sure.
In the previous bull run, it was ~$260.
