The bitcoin is safe but its depending on how you are looking at it indeed, if you are talking about if its safe to invest, I would say that it stays a investment of course.
If we talk about storing its pretty safe for sure.
When it comes to investment bitcoin is never safe as in the first place there is no safe in investment it all involves risk and bitcoin has a history of price crash so that alone would already prove that our investment is not safe, we are like gambling here so do not put a big amount of money.
Indeed bitcoin is not pretty safe if you have investment and putting your all asset to bitcoin is not good idea.better deal or getting advice with the financial expert so that your asset will not get busted.
