Bitcoins investment is safe if you just buybthem and hold all your bitcoins but when you decided to invest those bitcoins you have into a project that makes it not safe because not all projects are legit the technology today is pretty easy to use so it is now easy to do a scam too. Some people are getting scam because of investing in an allegedly bitcoins investment but for me if you really wanted to hold bitcoins just simply buy it and hold into a wallet there are a lot.of wallet apps here in the internet jist think wisely.
