Is Truecrypt still safe? [duplicate]

This question already has an answer here:

• Is TrueCrypt not secure now and should I stop using it? [closed] 3 answers

I want to fully encrypt a disk on Windows 7, but I don't trust Bitlocker and Truecrypt has announced it is not safe (also many rumours about NSA being able to decrypt it and it's better to avoid it).

So what can I use? Open source is better, and what is the most secure encryption combination today?

I see many people still use Truecrypt. Are they at risk of anyone easily accessing their data?
