This crate is overall pretty reasonable. It's not an insane voucher hack like the original January key or the Ice key, it's not a scam like the February key. It may appear worse to you on the surface than it really is, because a lot of its value comes from the February keys it dispenses in large quantities.
On average, it returns 39.7% of your money in vouchers, and it offers 3.7m in in-game value per effective dollar spent along with an estimated US$0.76 in IRL value (Invaded ranks, cosmetics).
If you just want to gamble, there's nothing wrong with buying this. Just be aware that this is definitely still gambling and not a sensible way to get vouchers or in-game stuff. 3.7m/USD is probably less than the current IRL rate, but you may consider this to be offset by the IRL-value offerings.
