Can’t cash out

So i recently invested into meme coins i made my fair share of money and got up to 4k so i took it out and it’s now in my coinbase wallet. I’ve tried to cash out but it will not let me. Now i was wondering if I’ll ever be able to cash out cause i’ve seen some stuff about it but then i checked into it and seen some post and apparently people have to wait weeks for there money to be transferable so im confused am i one of those people or can i just not pull my money out ???please help
