# Sending & Receiving

* ALWAYS CHECK THE FIRST AND LAST FOUR OF SEND/RECEIVE ADDRESSES
  * There are malware programs that can detect when you have copied a crypto address and swap it with one of their own. An easy way to prevent this and also prevent you from accidentally sending stuff to an incorrect address is to double-check.
  * When you check, do so against the original record, not what’s in the clipboard or a text message. Look at the ORIGINAL record. So if you got the address from Binance, look at Binance when you double-check it.
* There may be times when you cannot purchase something and need someone else to do it, or there is a specific whitelist or presale that requires you to blindly send crypto and trust that the dev will send it back. Understand there is always a risk you will lose everything you send.
* Only send crypto to people you trust and, preferably, have met in real life or are truly doxed
* Whitelists outside of the Wolf Den are always a risk. Do not send more than you are willing to lose
* Also note that when you are sending crypto to centralized exchanges like Coinbase, Binance and Kucoin the addresses do not stay the same. So do not save them in an address book, always get the most up-to-date address so you are sending them to the correct one.
