You are interested in shit coin. You know that this has much risk. Or didn't you get any other safest project to invest. Though you select, your money, your risk, your profit or your loss everything is your but you want help thats why you post it here. I think this problem is comes after pancake swap version upgrade. And the safemoon all liquidity is in v1 but you are trying to buy through v2 thats why you can not swap it. You just select v1 and try Again. If still problem not solved then you might choose wrong contract. Go to safemoon official website colect the right contract address and paste it on pancake swap you might get right coin and your problem might be solved. If still not solved then i don't know any other way. Thank you
