I would ask anyone what is safe in life these days? Almost nothing if we are to be honest, but if you do not risk you do not have to even hope for anything in life. I agree that there is no 100% safe trading in cryptocurrency, but also in trading stocks, real estates, or sports betting - everything is risk. The key thing is to reduce the risk to the maximum extent possible, and when it comes to crypto trading you need to know everything releted to that and that takes time.
People usually have doubts regarding money they need for start trading, or best exchange to start which is wrong thinking and mostly leads to losses. First learn about trading, take small amounts of money which you can afford to lose them and go step by step, maybe you will discover a real trader in yourself.
Be educated, be smart like a fox and persistent, reduce risk and you can expect success
