bitcoin is relatively safe, in the long term, don't look at the short term, plenty of manipulation going one, bitcoin need still plenty of time to grow
when everything about its problems will be settled, i beliave you will see the real usage of it, big merchants are waiting that after all, no reason for them to not accept bitcoin
The use of Bitcoin is safe and I can assure that if you do not attract attention that nothing is going to happen to you or your account.
Just keep everything for your self like you do not exist.
This is safer that transacting online using your bank accounts and even in remittances, with the blockchain you can see the transactions transparently so the transacted party cannot deny if he do something stupid against you.
