Solana to $1000 is likely given that the market cap is still rather low.
$300b market cap is very possible for SOL because SOL is a good project, has a good team, and social following/mentions. The more people become aware of Solana, the faster this coin will grow.
if we look at the graph of SOL it is clear why SOL can continue to reach ATH because the ups and downs are very fast and this indicates that trading on SOL is very active. Unfortunately, the upward movement will always be followed by a correction so that the movement to increase quickly seems to be stalled.
I agree with you SOL is indeed a good project from trading alone already looks active. but it must continue to be maintained in the long term if it can reach ATH but unfortunately it is always corrected. but I'm optimistic that SOL will make it to $1K, but maybe not this year. the possibility will occur next year if there is no correction which usually occurs at the beginning of the year. if it happens, maybe the end of 2022 will only be realized.
