I don't really agree with your statement that Solana flew under the radar for years before it popped off. If you do a little research then you will see, that Solana was only tradeable for a few monts before it started to see a sharp increase in price and also in trading volume. Now it is among the top 10 crypto projects in terms of market cap which is quite a big achievement.
Regarding your question if 60$ per SOL are possible in 2023 then i would definitely say "yes" that is definitely possible. At the moment SOL is trading at around 32$ and it's ATH from like 10 months ago was at 260$ so i don't see a reason why SOL should not reach 60$ if the crypto market recovers.
