Luna was a very bad investment to those that invested in the coin, but again it's a hard lesson to learn. There is a saying "never guide all your eggs in one basket 🧺". You said you lost too much of your life savings but if you had invested in at least three different coin, you would not have loss Total because you will still have had investment in other coin.
   The Luna crash wiped out some investors funds. example was the Korean investor known as “Chancers,” he lost $2.4 million on Luna coin and later got arrested after knocking on Do Kwon’s door (https://news.bitcoin.com/luna-investor-arrested-for-knocking-on-do-kwons-door-after-losing-2-4-million-in-terra-crash/).
