I have some questions
Will btc continue rising or will drop and fuk everything up
I'm not sure if you understand what Bitcoin is really about but nobody can tell you what will happen and the last time I check, I never see where Bitcoin fuck everything without making ammendment, as long as you didn't sell, it might go down and will still go up again after sometimes, so I'm not really sure if what you mean is Bitcoin to go down like meme coin, if that's the case then it's not possible.
Not coin is it safe to enter this coin now
Does bitcoin effect memecoins on solana or base
Notcoin in their Twitter has a bio description as probably nothing, you should invest at your own risk. Bitcoin affects every other coin, not just only Solana and meme ecosystem but the entire altcoin ecosystem, like today Bitcoin had some correction and many altcoins followed badly including the notcoin you asked.
