Telling all of your friends might not be a good idea
I second that, and the situation could be worse for people who do not know how to create strong passwords, anyone who doesn't know how to create strong passwords, read:
How to create strong/secure passwords. If you use weak passwords like names, dates of birth or something personal to you, definitely your close friends would have those information about you, and if they think you're rich and get jealous, they can try to attack you if they get access to your device; they could even try to hack your bitcointalk account, if you've also told them about that.
As a university student (like myself) it's even more difficult, sharing a house with other kids, and it's difficult to stay personal with lost of friends (knowing you need to write out seed phrases, private keys etc) I'm sure i would have lost a lot of my funds in cryptocurrency if i wasn't on bitcointalk (where you can learn how to stay safely store your coins, create strong/impenetrable passwords, stay anonymous etc).
