There is a million and one understanding to the word safe. When thinking of buying any cryptocurrency you have to look at the market,the value,the ups and downs. For now I can say it's ever safe to invest in bitcoin .and whenever you make that decision also think of a way you can gain per %of whatever you invest In daily. I say it's a good way to kick start. If you feel you have that already settled feel free to upvote or send a personal message for any furthers
