Of course, I believe that Bitcoin is very safe. There are several scammers, and that is very bad. But you have just to be careful.
And trust only the people you know and not every person.
Yes, bitcoin will be safer if you are fully aware on how to safeguard your bitcoins. Once if we are having all the required measurements to protect our bitcoin then getting hacked or sammed is very less possible, so that we can have our better stay with the bitcoin system for sure.
