A rug pull is a scenario in the cryptocurrency world where developers abandon a project after raising assets, leaving participants with worthless tokens.
Trading volume trick.
The number one any rug puller will make is try and increase the trading volume of his token, you will notice purchases bought/sold at the same instant with big amounts of money with little loss (fees), so for instance you'll find someone who bought with 1,026$ and sold for 1,021$ making 5$ loss which counts for fees, you will notice this kind of transactions happening a lot in short period, these are usuauly made using bots.
Rug pull checker sites.
It's crucial to use a rug pull checker sites
I recommend this site: https://rugcheck.xyz/
It will tell you if it's too dangerous to buy a token or not, Just go there, type the address of the token and press check token.
LP: means Liquidity provider, or the money provider, more like the bank that pays for those who decide to sell their tokens.
Mutable metadata: means the token information (Supply, name, symbol.. etc) if you see it, don't buy the token, because the creater can simply manipulate the token easily. make sure the token you buy is immutable.
Top holders.
on the rug checker site i provided above or if you check the top holders of the token, you should not see a pattern, meaning, you shouldn't see the top 5 holders hold the same exact number of tokens, the following picture represents a token that the top 5 holders hold 5 m (5 Million) token each.. this is not normal.
Try not to jump into newly created tokens without at least checking the above, it's better to be later for 2 minutes than loosing your money.
Trade safely.
