No I never think it is safe investment because knowing how bitcoin grows there is a chance of crash on anytime that make it a risky investment but we can't deny the fact that it really attracts lots of investors that makes it a good investment indeed.
You're right, but every investment has that much risk one way or another. Many people who took that risk with btc already ended up millionnaires in less than a year this year. So believe me dude, it's really risky yes, but it's worth the risk
