Hello Everyone, hope that you all doing great.
So, in the past few days i opened my exchange crypto -> crypto service and already has some geeks trying to scam me.
i'm here to warn you to not getting scam in these little nerd guys
First of all when you get some client that want to exchange with you and won't use MM be careful because they will try to Double Spend you.
What is Double Spend?
"Double-spending is the risk that a cryptocurrency can be used twice or more. Transaction information within a blockchain can be altered if specific conditions are met. The conditions allow modified blocks to enter the blockchain; if this happens, the person that initiated the alteration can reclaim spent coins."
That means if he send you as example, Bitcoin and want you to send him something instantly like Litecoin that shows that he will try to scam you with that method.
He will send you first, but worried about you send him instantly and he will keep presure.
After he sent the crypto he will expect that you send instantly because his fees will be about 0,03 ( 1 satoshi ) that will takes days for you to receive and yours faster.
He doing that and with txid, he will not get 1 confirmation, always wait for 1 confirmation until you send the money for that client.
Mempool
Use mempool because this way you can see if the transaction was replaced.
Example
