I could'nt say that bitcoin is very safe for all stake holders. We all know that for now, Bitcoin is decentralized that we dont even know where can we find our midman . But i still believe in the future that Bitcoin will be the safest among the currency in the world.
I think we cannot tell if bitcoin is really safe for all as bitcoin is decentralized and sometimes others people account is not safe once got hacked, so it really depends how we use bitcoin.
