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
i suggest invest in tron it should be best option for this year. investing in one coin doest seems bad for you. but spliting thr coin is not bad idea cause you might got a profit from one of the coin you hold and you. able to hold and sell it at the same time.
