Crypto pump and signals

Assalamualaikum, I don’t know much about crypto but recently I came across a telegram group that helps in crypto pump and signals i.e they tell us the crypto to buy, when to buy and sell it so we can gain money.
I want to know if it’s halal to do something like that

Wa alaykum salaam,

The exact nature of what is being advised is not clear from your question.

Oh, I’m sorry, so I joined a telegram group where they tell us to invest a certain amount of money in a crypto, then after 5 mins we sell the crypto off and remove our gain.
Now is it Halal to do things like that?
Thank you.
