Nope they are not safe yet, you will loose money if you buy high. Now is not a good time to buy people.
Why not, maybe the price of bitcoin won't go lower in 2016 or ever.
Buying now just little amounts is good to do, only if you do a long term and holding it is a good idea.
Indeed, it's better to buy now, I don't think the price will drop again lower than $350.
If it does you're lucky to buy in then.
