Its not that bad to put your real money in it because you can later make some good profit with Bitcoin and that is quite not that bad if you are doing good, it takes a long time only.
There are also a lot of people that dont trust it because they think that you can be hacked but that is not true and Bitcoin is safe so that is nice.
I actually agree with your first point, that it is not bad to put your real money in bitcoin because you may get a good profit later from it.
But, i don't really agree with your 2nd point.
Bitcoin is not really safe as you are thinking, maybe it is safer then other currencies but there are people who also can hack a bitcoin wallet and steal all your coins and run away.
It is only you who can secure yourself and make yourself safe from thieves and hackers, just pick the best wallet from all given options and make it fully secured before adding all your coins in it, and also it is better to keep your coins in different wallets so that you don't lose all of them in case your wallet is hacked or stolen.
