It is a big risk to go all in.

How much you have to invest is not really important for that decision, you should always diversify a bit even if you start with $50.

I suggest you to split in 3, for something a bit safe $200 in BTC then $150 in 2 others projects.

or you can try something like this :

$200 in BTC
$150 in STRAT
$75 in an other project
$75 in an other project
