I never give these kind of advices why would i need to say: use 2FA with your online wallet in the middle of saying print your priv key and hide where you think it's safe (hodl it codl). Thats beeing said it was my hot wallet where i stored more then i should, i didn't used 2FA cause i need to access my wallet many times a day and scanning the QR(or reading emails/sms's) code every few minutes is is stupid keeping mind that i should do it many times.
